The tester worked surprisingly well – it was able to correctly identify BJTs, FETs, even esoteric parts. The only thing it balked on was a linear voltage regulator, which showed up as two diodes.

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced.

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.

Up to the present, stabilization has either been by minimizing these effects by suitable circuit design, or by the use of thermistors and non-linear elements in the base circuit.

For example, you can insert a resistor, a capacitor, an inductor, a diode, or a transistor and get a readout of which pin is which.
