What is ceramic capacitor used for.

A ceramic capacitor is a fixed value capacitor where the ceramic material acts 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 applications. Many geometries were used in ceramic capacitors of which some like ceramic tubular capacitors and barrier layer capacitors are obsolete today due to their size. Ceramic disc capacitors are used across brush dc motors to minimize rf noise. Depending on the shapes and sizes they are used as feed through capacitors electro magnetic interference supressers and even as power capacitors in transmittors.

The first ceramic capacitor was disc shaped and now it is available in different shapes and sizes. Within the ceramic capacitor family there are many forms of ceramic dielectric that are used. When the ceramic capacitor are layered multiple times it becomes mlcc. Following is the symbol for ceramic capacitor.

Bmi surplus offers a broad range of new and quality used capacitors in the used electronic test equipment product category. Ceramics were one of the first materials to be used in the producion of capacitors as it was a known insulator. Ceramic capacitors can also be used as a general purpose capacitor because of their non polarity and are available in a large variety of capacitances voltage ratings and sizes. The ceramic capacitor gains its name from the fact that it uses ceramic materials for its dielectric.

Non polarity device means the capacitor has no polarities.
