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 ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, ...

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 ...

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, ...

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

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

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 ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...
