A capacitor is an electrical component that stores an electric charge and is used in filter circuits, since AC signals pass through while DC signals are blocked. Televisions use a large number of ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

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 ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...

Capacitors fail. It’s what they do. Aluminum electrolytics caused my monitor power supply to fail. A failed capacitor took down Paul Rako’s air conditioner. This is a story of how two burned ...

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

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 ...
