This black aluminum heat sink measures 4" x 2" x 1-1/14" with a 2" x 2-1/4" base. (6) 5/16" thick fins at the top and a set of (5) more at the bottom above the base. In between the fins is a 1-1/4" x 2" space for your chip with a 1-1/8" square thermal pad and a 3/16" bore.
This thermal fuse has 1.6 ohm resistance at the terminals, so at 6V should handle up to 3.75A. Housing measures 1-1/4" x 3/4" x 5/8" with a pair of 3/16" terminals on the bottom. Normally closed. Made in the USA in the early '90s for use in a Power Wheels® battery in a Super 6™ Volt Vehicle models 85000-85999, PP940 AND PP941.
These single-digit displays with (8) LED segments in a DIP draws approx 150mA between 1.5 and 2.5 VDC. This is numeric because some segments' pins are internally shorted. Common cathode ground. Yellow segments. Measures 28mm x 17.5mm with 13 pins.
Good things come in little packages. In this case the package is a 1-1/4" x 1-1/4" x 1/2" modulator, and the good things are a circuit board with at least a trimpot, electrolytic capacitor, assorted coils, 3-pin connector, RCA plug and (2) pop-off covers. Have a blast.
This little (12mm dia x 8mm thick) transducer makes that ultra-annoying buzzing modem sound, because it's made for a modem. Apply a square wave signal in the 2200Hz range at approx 6V and it will buzzerate for you. Well, who wouldn't? Sound pressure level is about 85dB, 80 Ohm impedance. Housing is marked for polarity. Printed on the top is RDI-DMT-1206. Application notes are at www.microchip.com, reference AN655.
Remake, recycle and reuse this repurposable Personal Response System remote. Made for answering test questions in college classrooms, this PRS TX-02 remote is now discontinued but full of lovely parts and waiting for a new electronic home. Inside you'll find a 940nm IR LED, a 12-digit touchpad, 2-C9015 PNP transistors, a red/orange/green LED, a 3.5795454 MHx crystal and a couple of ICs. As is, no guarantees. And let's keep it legal, OK?
