Ceramic capacitors are a type of capacitor made from ceramic materials. They are widely used in electronic circuits due to their low cost, stability, and resistance to environmental factors such as temperature and humidity. The construction of ceramic capacitors typically involves sandwiching a thin layer of dielectric material between two metal electrodes. The dielectric material is usually made from a type of ceramic called barium titanate or calcium zirconate. These materials have high permittivity, which allows them to store electrical charge effectively. Ceramic capacitors are available in various forms, including disc, tubular, and surface mount types. They are used in a wide range of applications, including filtering, decoupling, and coupling circuits.
