Ceramic Capacitors

A ceramic capacitor is a fixed-voltage capacitor in which the ceramic material acts as the dielectric. It consists of two or more alternating layers of ceramic and a metallic layer that acts as the electrode. The composition of the ceramic material determines its electrical behavior and, therefore, its applications. Ceramic capacitors are divided into two application classes:

Class 1 ceramic capacitors offer high stability and low losses for resonant circuit applications.
Class 2 ceramic capacitors offer high volumetric efficiency for buffering, bypass and coupling applications.
