ITEM SEARCHES, EQUIVALENT ELECTRONIC PARTS: Please use top-right search box (or your Browser Search / Find feature) to locate the specific Items of interest or just browse webpage. We listed many electronic parts by more than one name and name variation (e.g. "10mH", "10 mH"). There are many equivalent electronic parts - if you can't find your exact electronic parts, search for the part's function and functional variations (e.g. "inductor", "coil"), and by core electronic part # or descriptor (e.g. Enter "mH" to find every inductor and transformer listed herein with inductances in millihenrys). Top-right search box finds parts even if you only have small snippet of name or part #. If you still can't find your electronic parts, try by other name and part # variations. If you still can't find electronic parts then search our other likely webpages, see SITEMAP for links. Your efforts might save you money as some electronic parts / electrical parts are now either unavailable or rare and costly - if you can find more common electronic part equivalents and/or buy in quantity, savings of 90+% per part are possible.

Inductors, Coils, Antennas, Ferrite Cores, Ferrite Beads:


(15) 5mH INDUCTORS, 11ohm SHIELDED
"BRAINWAVE" INDUCTORS / "BRAINWAVE" COILS

New old stock (NOS) 5 mH inductors, shielded. These shielded inductors are square and about 5/16" on a side and 3/8" tall (excluding pins). Coil is center-tapped (3-pins). Inductance is tunable from about 3mH to about 7.5mH (nominally set at about 5mH). These 5mH inductors are very useful in a variety of designs, including signal, RF, pulse generation, pick-up coil, transmitting coil, etc. We mostly use them to design some brainwave detection devices as they are sensitive to brainwaves.

Several things make these inductor coils ideal for brainwave and mind control research and applications: (1) Relatively high inductance for small physical size. (2) Small physical size for greater pinpointing of signals. (3) Outer shielding which not only minimizes the pick-up of stray electromagnetic fields, such as from power lines and transformers, but also provides physical strength to the inductor body. (4) Center-tapping for either tapping off two sets of signals isolated from each other, or for inserting a signal or DC voltage on one leg while inserting or extracting the resultant brainwave signal from the other leg.

Top of image shows top of inductor with ferrite cap intact, as well as with ferrite cap completely unscrewed and removed, and the thin top part of the inductor's aluminum case filed off so the coil is maximally exposed without removal from its shield protection, making it ideal as a partially-shielded pickup coil and/or transmitting coil. The bottom part of this image shows the inductor on its side as well as the removed ferrite cap on its side.

The SUPER CONDUCTOR DETECTOR

New! This exciting and incredible device detects virtually all nearby conductive materials without touching them - including as a metal detector for platinum, gold, silver, copper, aluminum - even carbon and some conductive composite materials - without touching the conductor - even through insulators like cloth / clothes, plastic, paper, wood and ceramic - even through flesh - even if hermetically sealed in an insulator! Especially designed for detecting and differentiating smaller conductive objects, such as coins, jewelry, watches, keys, metal hardware, and electronic implants (with conductive shells or innards). Highly directional to pinpoint conductive objects. For those truly interested in gizmos with astounding and seemingly supernatural capabilities, you absolutely MUST buy the SuperConductor Detector!
           We are currently working on our Portable Gold Magnet based on this technology - a real gold magnet which actually attracts gold (not gold-colored magnets, or magnets used in gold panning to remove black sands, but a real gold magnet!). Stay tuned - we are making good progress and may have our Portable Gold Magnet soon. If and when we complete it, we will first offer it for sale to our good customers.
           NOTE: This device-type was handmade and hand-tooled in limited quantity using several different box types and circuitry, but all have the same functions and features as described above. Therefore, the device you receive may differ in appearance from the one in the image above. Lid to device box may be shown temporarily opened or removed for better view of internal circuitry. Please allow 3 weeks for delivery.

(6) "RUBBER DUCKY" ANTENNAS / SCANNER ANTENNAS
VHF/UHF or SIMILAR RF ANTENNAS

New old stock (NOS) rubber ducky whip antennas, VHF/UHF (or similar) RF Antennas. 7-1/2" long. Base connector is a TNC male connector (a mechanical connector 1/2" diameter and is threaded inside; inside the base connector is a smaller BNC-size electrical connector for the antenna function itself). TNC-to-BNC adapters are commonly available on eBay (as low as about $1 each), and other electronics retailers. A BNC jack with the "ears" ground off connects up snugly with the antenna's electrical connector, and permits quick connect / quick disconnect operations. This radio antenna / scanner antenna is very high quality.

SUPER THIN FLAT COIL
SLIPS BETWEEN SLOTS, SLITS, JOINTS, CRACKS,
CLOSELY-SPACED PC CARD STACKS, OTHER THIN SPACES

New old stock (NOS). Very versatile and rare type of induction coil / antenna coil about as wide and thick as a credit card, and about 400µH inductance. Especially nice for stealthly slipping inside of electronic equipment through slots, slits, joints and cracks, and between closely packed card stacks to pickup and detect important signals and/or to inject certain signals into the equipment, such as control signals.

If you've ever tried to make a coil like this, you will appreciate just how very difficult they are to make. Even some advanced electronic shops have problems trying to make them. We currently have about 100 of these very rare handmade coils available for possible sales; this sale is for one of them; and prices will likely increase as my supply diminishes.

This truly remarkable inductor coil can be used as a receiving coil / pickup coil / near-field coil / transmitting coil, continuous wave or pulsed operation. Two can be used together as a very flat transformer, or as some type of a detection / analysis / testing setup (e.g. the object to be detected, analyzed, tested or processed is placed or occurs between the coils), as a "through-wall" set of communications coils (e.g. transmitting coil is laid flat on wall or other separator and receiving coil is laid flat on other side of wall / other separator opposite to the transmitting coil). Another major application is using two as miniature Helmholtz coils (Helmholtz coil pairs are commonly used with electromagnetic therapy equipment and with mind control devices). Another is as directional antenna coils for Technical Security CounterMeasure (TSCM) near-field probes (especially the magnetic component). Other popular applications include other directional antenna uses, small metal detector coils, coils for detecting / measuring / programming brainwaves (i.e. brainwaves coil for various brain research, biofeedback, and mind control uses), as a general biological signals pick-up coil, as a near-field magnetometer coil, and/or science fair projects. Because the coil is flat, it can be conformed around cylindrical, spherical, wavy and uneven objects and surfaces. Great for snooping around electronic equipment in situ, especially when small and tight spaces make snaking in any other types of coils impossible, so this coil's circuit electronic troubleshooting, and security and research applications are truly outstanding.

These spiral coils also have crafts, jewelry and decorative applications. Some folks believe that spiral antennas transmit and/or receive mystical, spiritual, healing, psychic and/or alien/galactic signals. In fact, wall art from several ancient civilizations appear to depict flat spiral antennas. They are certainly fascinating to study and experiment with.

Because these special coils are all handmade, there are minor variations between them.

LIMITED QUANTITY. We only have a handful of these left.

6' MAGNETIC TRANSDUCER / MAGNETIC PROBE /
MAGNETIC ELECTRODE / MAGNETIC FIELD PROBE /
BRAINWAVE ELECTRODE / BRAIN PROBE, 12mH, 25 Ohm

New old stock (NOS). These magnetic transducers / magnetic probes / magnetic electrodes / magnetic field probes / brainwave electrodes / brain probes can be used for both detecting/receiving and transmitting magnetic fields and as a small electromagnets, depending upon the piece of equipment it is connected to (under 250ma current). Originally bought for brainwave research, these magnetic transducers can be used for many applications, including but not limited to, brainwave detection, other psychic and paranormal research, other medical/biomedical research, small magnetic field detection, small metal detection, bug detection/tap detection (as well as bugging and tapping), some implant detection, isolated communications, material flaw detection, magnetic therapies, magnetic stimulations, magnetic key decoding, to measure relative motion of conductive objects (especially iron or steel, e.g. tachometer), etc. These magnetic probes are also ideal for many magnetometer and field-strength meter devices and uses.

Cable length is 6-foot and is of a very high quality and pliable coaxial cable (coaxial cabling is required to absolutely minimize electrical noise pick-up). These magnetic transducers are about 1/4" diameter and about 1/2" long - an incredible 12 mH inductance, 25 ohm, for their small size. On the other end is connected a mini-phone plug (we also have a few each with RCA plug, sub-mini phone plug and spade lugs, so if you need one of these, let us know). These magnetic transducers will both receive and transmit magnetic energy from about 0.2 Hz to about 300 KHz pulse, modulated and sinewave signals - covering the entire audio frequency bandwidth (BW), as well as most of the infrasonic BW and air ultrasonic BW.

When used in conjunction with a commercially-available audio amplifier or recorder, these magnetic transducers should be wired in as a dynamic microphone. Both infrasonic amplifiers and ultrasonic amplifiers are also available from us.

For use with living tissues (plant or animal), penetration or even direct contact to surface is not required, however, contact should be as close to surface as possible as air gaps diminish effectiveness. This means that these magnetic probes are non-invasive, and one does not have to use a gel, shave the area, touch the skin or other surface, or suffer electrode irritation (common to skin contact and invasive electrodes) to effectively use it. And that these magnetic probes can be effectively used over most light clothing and plastic wrap. As with all magnetic transducers, especially those used for sensitive or precision magnetic detection jobs, the magnetic transducer should be held as steadily as possible. This can be done using a steady hand, rubber bands, velcro or shower cap with a hole in it to pass the cable or tape (none of these are provided). For permanent use and non-living area contact, you might also consider using a cement, glue or other firm adhesive to attach the transducer rock-solid to the surface.

This is just one electronic device in a group of closely related Items you may be interested in: (1) Ultrasound Amplifier, (2) Infrasound Amplifier, (3) Magnetic Transducer - this Item, (4) Ultrasonic Microphone, and (4) Soft-Pinch Electrodes. Email us if interested in ultrasonic, audio or infrasonic devices.

Note that these magnetic transducers are all unique handmade creations so while we have limited quantity, the one you get may not be the exact one shown in the image as there are minor variations in appearance (heat shrink tubing is used to reinforce both the magnetic transducer and connector ends so that even with much handling, this magnetic transducer should last a very long time).

After many hours of using magnetic transducers of this same type (the magnetic transducer you will receive is new and never used), including some outdoors uses, we have found them to be very useful, reliable and versatile, and have not broken one yet. This magnetic transducer does not have a built-in amplifier (not an "active electrode"), but the signals it picks up can be viewed on a quality oscilloscope.

This special magnetic transducer is not intended for any medical uses. We are not licensed medical professionals. We make no medical or paranormal (including but not limited to psychic powers) claims. This magnetic transducer can also be used for many electronic laboratory, shop, automotive and hobby / craft uses.

This magnetic transducer does not come with a User Manual, nor with any other form of documentation, nor with any tutorial, instructions or guide on its many possible applications and uses, nor with free consulting services. And it does not come with an amplifier, oscilloscope, additional cabling or any other hardware.

(20) 3.9mH / 3.9 mH COIL INDUCTORS 8mm Dia., 10mm High, ±10%, 200mA, 8.5 Ohms

New old stock (NOS). 3.9mH coils / inductors. About 1/4" diameter, 3/8" long, 10 ohms. We find these 3.9mH inductors (nominal 4mh inductors) are especially ideal for monitoring brainwaves for brain research and mind control and electronic harassment research. They are ideal for power supply filters, and low-band filters. Because these 3.9 mH inductors are indented in the middle, they are easy to convert into custom-made transformers by wrapping additional windings using magnet wire. 3.9mH inductors shipped on reel strip.

Because these inductors are small, they are especially great for pinpointing localized and small magnetic field sources, which is often critical for brainwave research, surveillance, and where small magnetic field sources are near or inside larger magnetic fields, such as ambient magnetic fields. Because they are of relatively high inductance value, they are also especially great for detecting and pinpointing low frequency signals in the 1 Hz to 100 Hz band, which includes both brainwaves and AC power systems (60Hz and 50Hz). If you encapsulate the inductor with supporting pre-amp circuitry, this inductor makes a great power pick-up coil, signal receiver coil or signal transmitter coil for small electronic implants, RF receivers and RF transmitters. Versatile inductors  - great for many uses!

MANY RECEIVING & TRANSMITTING USES: These inductor coils can be used in both receiving and transmitting applications for frequencies (freqs) from a few Hz to upto about 2,000 Hz. To use these inductors to receive magnetic signals (e.g. for brainwaves, high-voltage line magnetic fields, hidden surveillance devices, audio bandwidth magnetic signals, etc.), you need an appropriate amplifier (amp) which has either a magnetic input or dynamic mike input. Then you connect wires and end connectors to these inductors which are compatible with your amp. These inductors have external leads for soldering up your wires. Amp bandwidth is critical. Many quality audio amps amplify down to about 15 Hz - 25 Hz. Some brainwave and magnetic field signals are of lesser freqs, and thus may not be amplified well by an audio amp, in which case, you use a very low freq magnetic amp. Magnetic amps do not supply current to the inductor's line. The fluctuations of the external magnetic field induces into the inductor an electrical current and thus into the input line to the amp, which current in the amp is typically converted into a voltage that is amplified by the amp. For transmitting uses, you need an output amplifier stage which will drive a small magnetic load. These inductors can of course be wired in series (e.g. for greater resultant inductance and output voltages) or parallel (e.g. for input signal mixing and greater transmitted magnetic field).

Note, that these are INDUCTORS - not mikes - so they do not pick-up sound directly - only fluctuating magnetic fields. Also note that this sale is for inductors only, and does NOT include cables, connectors, amplifiers, or anything else.

(20) MINI 8.2MH INDUCTORS / 8.2 MH COILS
72 OHM, 50MA, NIS00410

New old stock (NOS) SMT/SMD. Very small 8.2mH inductor coils (nominal 8 mH inductors), 72 ohm, 50ma, part # NIS00410. When iron is brought near these 8.2 mH inductors front, inductance increases by about 10%. This means that these 8.2 mH coils are great as pickup coils, for example, to pickup brainwaves and other magnetic fields - great for biofeedback, mind control and electronic attack research. These coils are very small - 3/16" diameter, 1/8" tall - in fact, tiny compared to their relatively very high inductances. And because these inductors are tiny, they are especially great for pinpointing localized and small magnetic field sources, which is often critical for brain research, surveillance, and where small magnetic field sources are near or inside larger magnetic fields, such as ambient magnetic fields. Encapsulated with supporting circuitry, this inductor makes a great power pick-up coil, signal receiver coil or signal transmitter coil for small electronic implants, RF receivers and RF transmitters. And these 8.2 mH coils are ideal for many passive filtering applications, for examples, lower cut-off frequency LC filters (high-pass, low-pass, notch and bandpass filters), and for filtering power supplies (especially switching power supplies). Truly remarkable inductors - we know of no other inductor with its capabilities! Comes on antistatic reel tape.

MANY RECEIVING & TRANSMITTING USES: These inductor coils can be used in both receiving and transmitting applications for frequencies (freqs) from a few Hz to upto about 20,000 Hz. To use these inductors to receive a magnetic signal (e.g. for brainwaves, high-voltage line magnetic fields, hidden surveillance devices, audio bandwidth magnetic signals, etc.), you need an appropriate amplifier (amp) which has either a magnetic input or dynamic mike input. Then you connect wires and end connectors to these inductors which are compatible with your amp. These inductors have small built-in soldering pads (as shown) for soldering up your wires. Bandwidth is critical. Many quality audio amps amplify down to about 15 Hz - 25 Hz. Some brainwave and magnetic field signals are of lesser freqs, and thus may not be amplified well by an audio amp, in which case, you use a very low freq magnetic amp. Magnetic amps do not supply current to the inductor's line. The fluctuations of the external magnetic field induces into the inductor an electrical current and thus into the input line to the amp, which current in the amp is typically converted into a voltage that is amplified by the amp. For transmitting uses, you need an amp which will drive a small magnetic load. Be careful not to exceed the 50ma output current rating, whether DC or AC; since these inductors are rated at 72 ohms, output voltage to one inductor should not exceed 3.6 VAC or 3.6 VDC. These inductors can of course be wired in series (e.g. for greater output voltages) or parallel (e.g. for both receiver and transmitter uses).

Note, that these are INDUCTORS - not mikes - so they do not pick-up sound directly - only fluctuating magnetic fields. Also note that this sale is for inductors only, and does NOT include cables, connectors, amplifiers, or anything else.

(15) 8.4MH INDUCTORS / 8.4 MH COILS
80 OHM, 100+MA, Magnetic Metals

New old stock (NOS). Magnetic Metals 8.4mH inductor coils (nominal 8mH inductors), 80 ohm. We run these 8.4 mH inductor coils at more than 100ma. When iron is brought near these 8.4 mH inductors front, inductance increases by about 10%. This means that these coils are great as pickup coils, for example, to pickup brainwaves, and magnetic fields - great for biofeedback, brainwaves, mind control and electronic attack research. And because the coils have a 1/8" diameter, almost 1/2" long hole in the center, see image, you can insert a permanent magnet, ferrite stud or iron stud (e.g. piece of 1/8" dia nail) to much increase the coil inductance for even greater sensitivity, to tune inductance, or to use these coils as solenoids or adapt as relays. And these 8.4 mH coils are ideal for many passive filtering applications, for examples, lower cut-off frequency LC filters (high-pass, low-pass, notch and bandpass filters), for filtering power supplies (especially switching power supplies), and for small audio crossover filters. These 8.4 mH inductors are 1/2" long and diameter of coil is 1/2".

Because these inductors are small, they are especially great for pinpointing localized and small magnetic field sources, which is often critical for brain research, surveillance, and where small magnetic field sources are near or inside larger magnetic fields, such as ambient magnetic fields.

Be careful not to exceed much beyond 100ma output current rating, whether DC or AC; since these inductors are rated at 80 ohms, output voltage to one inductor should not exceed 8.0 VAC or 8.0 VDC. These inductors can of course be wired in series (e.g. for greater output voltages) or parallel (e.g. for both receiver and transmitter uses).

(10) FEC0114 INDUCTOR COILS (FEC 0114 COILS),
VERSATILE & PROGRAMMABLE INDUCTORS, 8µH (8uH)

New old stock (NOS). These versatile FEC 0114 / FEC0114 inductors are about the size and shape of chess pawns. They are 1" long (excluding 3/8" long pins). Base diameter is 3/4", top diameter is 1/2". Top is mounted with a magnet. These FEC0114 inductor coils come as shown on the left with labeled heatshrink wrap, but this plastic wrap is easily removed with an Exacto knife to result in right image (heatshrink tubing works fine as a replacement wrap), which gives you the room to wrap another coil(s) directly on top of the existing coil for customized transformers. Coil resistance is about 0.03 ohms. Coil inductance is about 8µH (8uH) with no iron near coil top, but decreases to about 5µH (5uH) with iron near coil top. Top magnet is ceramic and moderately powerful, but can be demagnetized with a rare-earth magnet, in which case, inductance is about 36µH (36uH) with no iron near top and about 34µH (34uH) near iron body. Clearly, sensitivity is much higher with top magnet as is, however, you can partially demagnetize this magnet to fine tune the inductance betwen 8µH and 36µH. With wrap removed, you can modify the number of coil windings, and with the coil windings modified or unmodified, you can wrap additional layers of coil to make customized inductors or transformers. While three pins are shown, only two are connected to wires - the third pin can be ignored, clipped off or wired to something else. These non-documented features not only provide you great versatility in using these inductors in numerous coil and transformer designs, they also help you thwart efforts to reverse engineer your designs. You can also use these FEC0114 inductors to detect, count, control and tune rotations or movements of an iron or steel geared wheel or other iron objects where the rotating gear teeth or moving objects just clear the magnet (e.g. tachometer and assembly line designs). Or to detect and measure highly localized magnetic fields (for magnetic field strength meters). Other uses of these unusual and versatile FEC0114 coils are obviously as chess pawns, and as insulated standoffs and wire tie-down points. As insulated standoffs, you can detect and measure voltage drops between two points on a wire strung between two of these inductor coils or wrapped once around one coil. Or to detect and measure electromagnetic leakage from an insulated wire.

LARGE, ADJUSTABLE STEEL INDUCTOR COIL
Great for Theremins, Antennas, Metal Detectors, Tank Circuits, Crafts, Toys, etc.)

Used and in very good condition. We purchased this in an electronics surplus store. These large springy metal inductors have practically endless uses ranging from electronics, crafts, toys, model making, science projects / science fairs, etc. Compressed, they are 2-1/2" diameter and 2-1/2" long. The conductor coil itself is about 1/8" wide and 1/32" thick. It fully expands to about 10 feet long. Inductance varies from about 240 µH (240µH, 99% compressed) to less than 40 µH (40µH, extended to about 6 feet).

If you hold both ends and extend this metal inductor, it will sag in the middle. What we normally do is use a wood or plastic (not metal) broom handle, dowel rod, 2"x2" lumber, or heavy-duty carboard shipping tube as a stiff form to string the inductor out on to maintain spring shape. For those uses, such as antennas, where we need to keep the inductor length constant, we cement the ends to the form, and sometimes spot cement some of the spring coils in between.

we love to use these inductors in the tank circuits of homebuilt Theremin devices. A "Theremin" is an audio special effects device that dates back to about the 1920s, commonly used in those old horror and science fiction movies to produce those scary sounds. By expanding and compressing the coils, the circuit's LC tank circuit inductance is changed, thereby also changing the output frequencies, resulting in very unusual Theremin-like sounds. Similar sounds can also be produced by rubbing, flicking or moving the coils with an insulated iron bar. You can get endless hours of fun and entertainment out of it, and it has real potential of being developed into its own unique musical instrument to produces the really cool and unique sounds for some of today's music.

This inductor also serves as a pretty good antenna and metal detector coil. It has many exciting uses for the electronic hobbyist, and for science projects, science fairs, and classroom demonstrations. It can be used as a big, strong electromagnet because of the strong magnetic field it can be made to produce.

It also has crafts and shop uses. For examples, it can be used to make toys of various kinds, as well as other craft creations, such as lamps, figures, etc. And it can also be mechanically used to protect, reinforce and organize many different kinds of items such as bundles of wires and cables, long tools, tubes, pipes, rods and other shop stock.

This inductor looks a lot like a "slinky" toy. If it is a "slinky" toy it is not like any slinky that we played with as a kid, which were much larger and less springy feeling and not designed for electronic uses, and which we have never tested electronically.

6-COIL ELECTROMAGNETIC COIL ASSEMBLY

New old stock (NOS). 6-Coil Electromagnetic Coil Assembly. Great as a motor stator (especially for spindle motors, servo motors and stepper motors), to create rotating magnetic fields, and for science projects. In fact, these were salvaged from the spindle motor of a new very high quality but obsolete floppy disk drive (few floppy disk drives have a coil arrangement like this). Coil board measure 3" x 3-1/2". Coil center-to-coil center spacing is 1-1/2". We don't know who makes this board. The IC is a BA6492FS, FDD Spindle Motor Driver IC for 3-phase, full-wave, soft switching motors. We find these multi-coil assemblies to be very useful for experimenting with rotating magnetic fields relevant to our research in radionics, mind control and electronic attack, because all the coils are virtually identical to each other with precise spacing - perfect for generating precision rotating magnetic fields. (NOTE: If you can sell us more of these boards or of similar coil assemblies, please let us know as we are interested).

1.0:1.3, 450 Ohm - 600 Ohm, 300 Hz - 300 KHz, 2-Coil
SIGNAL TRANSFORMERS / WIDEBAND TRANSFORMERS

New old stock (NOS). Tamura TTC-264 / Microtran TM105 Audio Transformers / Ultrasonic Transformers / Signal Transformers, 1.0:1.3 Turns Ratio, 450 Ohm - 600 Ohm, 300 Hz - 300 KHz Bandwidth, 2-Coil Wideband Transformers. Most other signal transformers we run into that are 600 Ohm - 600 Ohm or similar are either strictly audio or strictly ultrasonic but don't cover both bands. These Tamura TTC-264 / Microtran TM105 Transformers are very versatile for audio, ultrasonic, sonar and many switching power supply applications. And you get a bit of a voltage boost out of them while not adversely affecting impedance too much, so these transformers are also very useful where that extra voltage boost is helpful.

ISOLATION TRANSFORMERS /
RF TRANSFORMERS / SIGNAL TRANSFORMERS, Hi Rel 11476

New old stock (NOS). We bought a ton of these - and am selling my extra stock. These isolation RF / signal / pulse transformers have 2 sets of windings with the same inductance (2.5mH) and resistance (2.5 ohm) on each side. The coil is a spool-wound coil with a ferrite shroud, 1/2" diameter. 3 pins on each side (middle pin is center-tapped), with pin-to-pin spacing of 3/20" (which means that the end pins are 0.3" apart), and spacing between pin rows of 9/16". Because the inductances and resistances are equal on both sides, these make great 1:1 isolation transformers. And because these transformers are center-tapped, you can do 1:2 step-up and 2:1 step-down transformer applications with them.

These are spool-wound transformers (not torroid/toroid transformers), which means that if you remove the ferrite shroud, you can use them as metal detection and magnetic field pick-up coils / transducers. This is really nice because what you can do is inject a high-frequency signal into one set of windings and observe the isolated output of the second set of windings as modified by metal or magnetic field the transducer is exposed to, thereby detecting the presence and quantity of the metal or the presence, intensity, frequency, duration, waveform and modulation of the magnetic field. For example, we found that these so-modified small transformers are excellent for studying brainwaves and brainwave signatures, biofeedback, electronic implant detection, etc. for my work for Consumertronics.net and Lone Star Consulting, Inc. For some of my many mind control, electronic attack and biofeedback publications and hardware We are selling, please see my webpages. Other great applications we get out of them is antenna isolation, high-voltage section isolation, and SCR triggering.

I found that removal of the ferrite shroud is best done by using a small grinding wheel to carefully grind off the ferrite bridge at the top of the coil (across the label), at which point the shroud comes to pieces and is easily removed. When the ferrite is removed, the about 1/4"-thick spool has a 3/16" through center hole, where you can boost some of the inductance lost due to the removal of the shroud by inserting a piece of ferrite slug or soft iron rod (e.g. an iron nail head).

(5) VERSATILE / ACCESSIBLE UMEC UT20145
ADSL POTS PHONE LOW PASS FILTER BOXES

These new Umec ADSL Pots UT20145 telephone low pass filter phone boxes are really great, especially for the experimenter! These were originally made for - and still function very well as - line filters for DSL applications. The enclosures themselves are heavy-duty plastic 4" x 2-1/4" x 1". As you see, the circuit board is easily removed, letting you use this nice enclosure for prototype projects you may be working on - high quality substitutes for expensive Budd boxes. It has a flange that protrudes from the base 1/2" on each side with a center hole for convenient mounting. The board itself has 3 RJ-11 phone jacks: One phone jack for the Line, one for filtered Output and one for unfiltered Output. The PC board also consists of sets of series inductors and parallel capacitors used to perform the low pass filter function. The enclosure cut-outs for the RJ-11 connectors can be used for other connectors, or you can cut off the RJ-11 connectors from the boards and mount them on your own circuit board. RJ-11 cables are very common and inexpensive, and can be used for many phone and non-phone applications. The 3db cut-off is 7 KHz. Attenuation is 12db at 8 KHz, 60db at 20 KHz, and 72db at 40 KHz. Insertion loss from 200 Hz to 4 KHz is 0.5db. These connectors, inductors and capacitors can easily be removed, changed or added to should you need to change your low-pass filter characteristics or even to change the filter to bandpass filters.

HIGH-TECH EXPERIENCED PROFESSIONALISM: Many "high-tech business" owners and their employees today are clearly woefully ignorant of the high technologies they sell (including some giant electronic parts houses!). ABQ Techzonics of Albuquerque, NM, USA, is owned by John J. Williams, M.S.E.E. Mr. Williams is a former Senior Electronics Design Engineer (Lockheed EMSCO); Professor of Computer Science (New Mexico State University (NMSU)); Electronics Weapons Design Engineer (U.S. Navy, U.S. Air Force); Health Physicist (National Institutes of Health (NIH)), etc. Williams is also currently President of Lone Star Consulting, Inc. and CEO of Consumertronics.net. While we don't know everything about everything tech (no one does), we have a high level of expertise. We sell a lot of electronic components / electrical components. Most of these electronic components / electrical components are small electronic parts / electrical parts, such as integrated circuits, optical devices, transistors, rectifiers, diodes, transformers, inductors, capacitors, resistors, displays, switches, relays, crystals, oscillators, transducers, sensors, prototyping, connectors, fuses, wire/cable, power components, etc., as well as some larger electronic parts / electrical parts and electronic test equipment, scientific equipment and industrial equipment / parts, electrical equipment / electronic equipment in general, tools, mounting hardware parts, and special materials. And we also buy and trade these types of items (Trade & Buy Offers). And unlike most electrical / electronic components sellers, many of the electrical / electronic component, etc. lots we buy we set aside some of the electrical / electronic parts, etc. for our own electronic projects and research. We sell those electrical / electronic parts, etc. we don't use. Our suppliers know that if their electrical / electronic parts, electronic test equipment, etc. aren't excellent, good chance we will discover it and they'll hear about it!
