Ceramic capacitors are a type of passive electronic component that store energy in the form of an electric field. They consist of two metal electrodes separated by a layer of ceramic material, which acts as the dielectric. The ceramic material is typically a type of oxide or titanate, and its properties allow it to withstand high temperatures and maintain its capacitance over a wide range of frequencies. Ceramic capacitors are widely used in electronic circuits due to their compact size, low cost, and reliability. They are often used for filtering, coupling, and decoupling applications, as well as for bypassing AC signals in audio and radio frequency (RF) circuits.
