Ceramic capacitors, often abbreviated as CERs, are a type of capacitor that employs ceramic materials in its structure. They are widely used in electronic circuits due to their reliability, low cost, and compact size. The key characteristic of ceramic capacitors is the use of ceramic dielectric materials between two metal electrodes. These components provide a stable capacitance value over an extensive range of frequencies, making them suitable for applications requiring low-frequency filtering or coupling. Ceramic capacitors are available in various types, including disc capacitors (CC) and multilayer ceramic capacitors (MLCC), each with distinct design features and performance characteristics.
