When choosing capacitors for power supply circuits, the rule of thumb of "electrolytic for large capacity" and "ceramic for high frequency" is a useful starting point. However, in actual devices, even ...

Ceramic capacitors are passive electronic components constructed using a ceramic dielectric. Ceramic materials have been used as insulators since the beginning of the study of electronics. Early ...

Medium- and high-voltage capacitors find widespread use as snubbers or filters in applications, such as switching power supplies for audiovisual and business equipment (computers, modems and fax ...

Rules such as “use electrolytics for bulk energy and ceramics for high frequency” are useful starting points, but not complete design methods. Two nominally 100-µF components can behave very different ...

This article is part of The engineer’s complete guide to capacitors. If you’re unsure of what type of capacitor is best for your circuit, read How to choose the right capacitor for any application.

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

Electrolytic capacitors are small and readily available, but using them wrong could be an explosive failure. Learn how they work and how to use them. A capacitor is physically created when two ...
