Capacitors play key roles in the design of filters, amplifiers, power supplies and many additional circuits. Here's a brief guide to the different types and the applications they're best suited for.

A capacitor is a two-terminal device that consists of two conducting bodies separated by a nonconducting material. The material is known as an insulator or a dielectric. The construction of the ...

Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, ...
