A ceramic capacitor is a fixed value capacitor with the ceramic material acting as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore the application of the capacitors, which are divided into two stability classes:
- Class 1 ceramic capacitors with high stability and low losses for resonant circuit application.
- Class 2 ceramic capacitors with high volumetric efficiency for buffer, by-pass and coupling applications.
Ceramic capacitors, especially the multilayer version (MLCC), are the most produced and used capacitors in electronic equipment with a produced quantity of approximately 1000 billion pieces per year.
Moreover, some ceramic capacitors of special shapes and styles are used as capacitors for RFI/EMI suppression, as feed-through capacitors, and in larger dimensions as power capacitors for transmitters.

Famous quotes containing the word ceramic:
“He had first discovered a propensity for savagery in the acrid lavatories of a minor English public school where he used to press the heads of the new boys into the ceramic bowl and pull the flush upon them to drown their gurgling protests.”
—Angela Carter (1940–1992)
