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 ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

Ever wonder what goes on inside of an electrolytic capacitor? Nick Visic from AiSHi Capacitors shows how these popular capacitors work in this tear-down video from DesignCon. The screw terminal ...

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 ...

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, ...

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 ...
