Designed specifically for applications that require repeated flexing such as voice coils, linear actuators, and robotics, this wire is extremely supple due to it's high quantity of small strands and super "limp" insulation. At 0.032" nominal overall diameter, the #29 wire is only 0.001" larger than typical decoder wire, but instead of the normal 9 strands, it contains 51 strands of #46 (0.0015") copper wire. It will carry 600ma of current so it is ideally suited for most motor power wiring in Z-Scale, N-Scale and HO. If more power is needed in larger scales, just run additional wires in parallel. Perfect for steam locomotives which usually place decoders in the tender (no more derails). The #32 wire is extremely small for insulated wire with an overall nominal diameter of 0.023". It contains 18 strands of #44 copper wire and will carry 250ma of current. This wire is ideally suited for lighting applications that require flexing of the power connections (truck pickups on rolling stock, crossing gates, bridge lifts, etc. It is also well suited for some lower-current Z-Scale motors. The possibilities are endless.
#30 Insulated Hookup Wire
Our hookup wire is packaged in 50-foot lengths on handy notched spools to prevent unraveling on your workbench. This silver-plated solid copper wire takes solder very quickly and will easily carry 300ma of current. It is available in white, black and red and is excellent for wiring LED lighting, small motors, switches and many hobby projects. It is very handy as a durable intermediate connection between our Power Distribution Board (below) and our fine #38 magnet wire (above) where a run of a foot or more is required.
#38 Magnet Wire
This magnet wire is ideally suited for devices that draw less than 35ma current. Manufactured by Superior Essex, Inc., this wire's small size (about .0045" diameter including insulation) allows it to be easily hidden or used as "prototypical electrical cable in actual wiring situations (see photos). The Soderon® insulation is quite durable and can be painted for further concealment or required effects. It is easily stripped as part of the wire tinning process. For easy use, we package it on a 2-layer bobbin.
Tiny Bridge Rectifier
Manufactured by Fairchild Semiconductor® as their MB1S, this little bridge rectifier is the perfect solution for lighting or other DC devices in N-scale rolling stock running on a DCC layout. Using a very simple circuit (see wiring tips), it will turn a pulsed DCC signal into DC to drive any device you might want to use, up to a full 1/2 AMP! It can handle up to 1.4Watts (1400mW) of power. Suppose you wanted to power our 3.6-volt 2x3 Super LEDs (our highest device voltage LEDs)... no problem! Using a 12-volt source, and series/parallel wiring, this little bridge could handle 18 of them! If need be, the contact legs can be folded under the device to further reduce its footprint .

12 & 18-volt Regulated Switching Power Supplies
1/10 watt, 1/8 watt , 1/4 watt & 1/2 watt SMD Resistors
Manufactured by Vishay Electronics and KOA Speer, two of the worlds largest makers of thick-film surface-mount (SMD) components, these tiny resistors provide the same power capabilities as their much larger axial-lead cousins. We've greatly expanded our selection to include a wide variety of resistance values in 1/10, 1/8, 1/4 and 1/2 watt sizes. The selection includes values specifically suited for current protection of our LEDs operating in either 9-volt, 12-volt, or 18-volt applications common to N, Z, HO & O-Scale DC and DCC, as well as values to allow the "tuning" of LED intensities for specific uses and projects. The Usage tables link above provides a comprehensive selection guide and the Calculators link makes custom tuning of LEDs quick and easy.
These resistors easily fit in the smallest spaces due to their flat, rectangular shape and miniature size. The solder pads on each end are pre-tinned for easy connection.
We also offer three different resistor assortment packs. A 9-volt pack, a 12-volt pack, and a 18-volt pack. A detailed listing of their contents can be found by clicking on either the Assortment Pack Item# or Desc. below
SMALLEST BRIDGE RECTIFIER
Miniature 16-volt & 25-volt Capacitors
Whether you're installing interior lighting in passenger cars, marker lights on cabooses, flashing rear-of-train devices, or cab lights in locomotives, nothing can be more irritating than watching the flickering that occurs when your rolling stock's wheels travel over dirt or gaps in the rail. Adding 500μf to 1000μf capacitance to your lighting circuit minimizes, and often virtually eliminates this problem.
Compared to typical film-wound capacitors these tantalum capacitors have a much smaller case size for the same storage capability. The N3100 is 100μf (microfarads) at 16-volts and is supplied in either a 6-pack or 24-pack. The N3068 is 68μf (microfarads) at 25-volts and is supplied in either a 10-pack or 40-pack.These capacitors can be "ganged" in parallel to achieve the amount of capacitance you need while still fitting in very small spaces. The 25-volt capacitors are ideally suited for HO power packs that exceed 16-volts DC, and most S, O and G scale power supplies.
Miniature SPDT Switch
Again, you asked and we've delivered. These single-pole double-throw (SPDT) toggle switches are a perfect choice for many different electrical wiring/switching applications. They can handle 6 Amps and 125-volts, and come in a handy 5-pack with all of the mounting hardware. They have an long threaded shank (3/8") for mounting in panels up to 1/4" thick. Center contact is the common wiper so they can be wired for on/on routing applications, as well as on/off.
The DCC Trak-Pak combines several of our products to provide easy adaptation of our lighting or sound effects to rolling stock for Z, N and HO scales. A complete list of what's included can be found by clicking on the Contents link in the More Info table above. We have used this product in an N scale cattle car to demonstrate our Little Bigger Sounds effect for cows, using our sound board, amplifier board and speaker, all located inside the car, running on track power. The effect is quite dynamic. To see the details of this installation, click on the Example of use link in More Info above. The Using link above completely covers adaptation and installation.
If you need an incredibly small SPDT switch to turn something on and off, or switch between two devices, we've got just the one for you. Made by ITTCannon, this little slide switch features silver contacts and will carry 150ma at 12 volts! To see just how small this little fellow is, click on the Compare size link above. Incredible! Mechanically rated at 10,000 cycles, it will certainly last. The sliding action has a positive "click".
Micro Bridge Rectifier
And... (drum roll please) for those of you who need a really small bridge rectifier, here's the industry's smallest! This little guy is the proud product of Central™ Semiconductor Corp. It will rectify 140ma of current and handle up to 50-volts DC on a continuous basis. It can dissipate 350mW of power, so with a 12-volt source, proper resistor for current control and series wiring, it could easily power 4 of our 3.3-volt 2x3 Super LEDs, and could power many more of our red and/or yellow LEDs.
Z-Scale enthusiasts: Space limitations for rectifying analog or DCC track voltage for lighting of any rolling stock is now history. This bridge rectifier will fit anywhere!
ANALOG AND DCC READY
DC Power Source
And.., and... (before the drum roll stops) for those of you who need a reeeeeally small bridge rectifier using schottky diodes for the lowest possible voltage loss (important for analog operators), combined with the industry's smallest 10μf multi-layer filter capacitor (important for DCC operation), all mounted on a tiny (0.320" x 0.150" x 0.085") circuit board with handy solder points. But wait... there's more.., it also has an additional solder point for direct connection of an LED plus solder pads on the back of the board for the LED's current protection/brightness control resistor. This module can rectify and filter up to 200ma continuous duty and can handle 350mW of power. With 12-volts as a source, it can support passenger car lighting or one of our Simulator modules and its LEDs. It can handle up to 16-volts, so it will support HO as well as N and Z scales.
LED Power Distribution Jr.
LED Power Distribution Board
The N8102 is designed to provide a convenient way to connect power to multiple LEDs from a single power source. It is ideal for lighting projects such as in model railroad structures, street lighting, dioramas, or anywhere that multiple LED light sources are needed. At only 1.40" wide x 3.40" long, the N8102 is packed with capability. Side A (front) of the board provides power for up to 16 LEDs by using highly-regulated 20ma current sources. These sources will support 20ma LEDs of any color and colors can be mixed within a group. Solder pads are provided for optional brightness-adjustment resistors to allow individual control of intensity of every LED if desired. Side-B (rear) of the board provides connection for up to 12 additional LEDs. These connections have solder pads for LED current control resistor placement. This module will support a power supply input voltage of up to 18 volts-DC. Nylon spacers for mounting are included with each board.
Just like its big brother above, this LED Distribution Board has a 20ma current source on the board top surface to provide highly-regulated current for up to 4 LEDs. This source will support 20ma LEDs of any color and colors can be mixed within the group. Solder pads are provided for optional brightness-adjustment resistors to allow individual control of intensity of every LED if desired. The bottom side of the board provides connection for up to 4 additional LEDs, which can be connected as one or more series groups, individually (parallel) wired LEDs, or a combination of both. These connections have solder pads for LED current control resistor placement. This module will support a power supply input voltage of up to 18 volts-DC. A nylon spacer for mounting is included with each board.
Constant Voltage Circuits for N & Z scales
Constant Voltage Circuit for HO, S, O & G scales
Configured for connecting up to three white, yellow-white, warm-white or
incandescent (3.3-3.6 volt) LEDs. Works well for most passenger cars, MOW cars
and cabeese (cabooses).
These tiny little circuits are the same small size as our Lighting Effects
Simulator boards (.310" x .310") and a bit thinner at .100". They use a very
tiny high-precision pass-through 3.3-volt regulator to maintain a constant
output voltage and can handle DC input (track) voltages of up to
16-volts. This makes them perfectly suited for N and Z scales. The
NL8014 is designed as a uni-directional
circuit for up to 2 LEDs with device voltages of 3.3 (standard "white
varieties"). It contains a schottky barrier diode that prevents the circuit from
functioning when track polarity is reversed which make this version ideal for
locomotive headlights operating in an analog (non-DCC)
environment. The NL8104-2 is a 2-pack of the modules.
This little board supports an extremely wide range of input voltage (up to
25-volts!) while maintaining constant output for
up to 3 LEDs. Unlike other circuits, ours uses a "pass-through" regulator, not a
buck or buck-boost type which keeps output off until regulation threshold is
achieved. That means that whatever the low-end track voltage is, it gets passed
through to the output. In short... the lights will start turning on at lower
voltages. Input is schottky bridge rectified to ensure the lowest voltage loss
and circuit power regardless of track polarity. Our N8104
boards are ideal for HO, S, O
G-scale using DC or DCC. Flicker control is maintained by
a powerful 680uf 25-volt electrolytic capacitor with the smallest case size
available in industry today.
If track voltages are AC, the upper voltage limit is
14.5 AC volts. This is because the RMS value (peak rectified voltage)
will actually be 20+ volts DC in the circuit.
These miniature capacitors are manufactured by Kemet and use a tin over nickel barrier for easy end solderability. Rated at 50-volts, these 0.1 microfarad ceramic capacitors will support a wide range of circuit voltages and are very useful for suppression of high-frequency or transient voltage spikes in electronic circuits. Their .125" X .063" case size makes them easy to handle yet small enough to be located in the most confining situations.

You asked and we responded! These highly versatile miniature circuit boards can be used for mounting resistors, LEDs, and other components and have thru-hole solder points for easy wiring. They are backed w/double-sided Kapton® tape which can withstand 500° F. Each strip of 10 boards is pre-grooved between the boards for easy separation (after tape is cut). Now, placing an LED with its appropriate resistor couldn't be easier - solder it up and stick it in place! These boards will support SMD resistors up to 1/2-watt in size and LED sizes up to our 2x3mm ones.
Our 5-pack of 3/64" diameter shrink tubing is back in stock. The package contains 5, 4-inch lengths of green polyolefin shrink tubing. Ideal for insulating those tiny decoder wires or any small wire that requires solder joint protection. 2:1 shrinkage. Shrink temperature 120 deg C (248 deg F) Operating temperature -55 to 135 deg C (-67 to 275 deg F). Can be painted with any acrylic paint after shrinking
This tiny device manufactured by Supertex is a high voltage, temperature compensated, constant current source. It provides a constant current of 20mA±10% over an input voltage range of 5-90 Volts DC, and can be used as a constant current source or a constant current sink. Multiple devices can be connected in parallel to provide higher current such as 40mA, 60mA, 80mA, etc.
These handy snap-on battery clips will connect to any PP3 type 9-volt battery (alkaline, NiCad, or Lithium). The snap connectors are nickel-plated steel for long life and the posts are tin-plated brass for easy soldering. The posts can be easily cut shorter for circuit board mounting applications.
These power supplies provide highly regulated voltage output so your lighting or special effects won't get fried.. Our new N3512A replaces the earlier N3512 we provided for many years. This new version has been modenrized with the thinner case like our N3518 supply and has been updated to meet current environmental requirements. It provides 12 volts and 1.25 Amp continuous-duty output, and is an excellent power source at a very reasonable price. It can handle nearly any lighting project and requires only minimal space. It can power nearly 200 white LEDs (using series/parallel wiring). The supply cord is equipped with a EMI/RFI filter to minimize electrical interference. This is a true switching power supply like the kind inside your computer. Unlike the "wall warts" (battery eliminators) available at many electronic stores for $8-$12, it doesn't use a transformer or have a simple two-diode circuit. And, it has over-current and short-circuit protection. The N3518 supplies 18 volts and .825 Amps continuous-duty output. It can easily power 225-250 white LEDs, and being 18-volts, it can easily power many 9-LED (red, yellow or green) series strings.
Our N3512 is now out-of-stock & has been replaced by the new N3512A (see details below)
