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, ...

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 ...

HDE's Cap Check line of capacitor testers is designed to identify internal problems with a capacitor or capacitor bank and have proven to be a valuable asset in maintaining both pole-mounted and ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

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