The Quick-Check Transformer & Capacitor Tester from HD Electric is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

HD Electric Co.'s Cap Check line of capacitor testers are designed to identify internal problems with a capacitor or capacitor bank and have proven to be a valuable asset in maintaining both ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual tolerance ranges afford. Precision matching of components from parts on ...

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

Used with a DMM on the 20V range, this circuit gives a rapid and direct measure of the leakage current of capacitors. There are two ranges, with maximum readings of about 20µA and 2mA, and the test ...
