Ceramic Capacitor

A type of capacitor created by adhering conductive metal to the two flat sides of a non-conductive ceramic disk. Electrical leads are attached to the two metal-coated sides. The assembly is then dipped in epoxy or other coating to seal it. There are four “classes” of ceramic capacitors, with the class refering to the stability, accuracy, efficiency and other characteristics of the capacitor. Class IV are obsolete, Class III are used for power supply applications, while Class I have high stability, accuracy, and linearity, and are used for filtering and signal applications.
