Ceramic capacitors, also known as Class Cer or Class I capacitors, are a type of electronic component used in various applications including filtering, coupling, and bypassing. They typically utilize ceramic dielectrics, which provide good stability over temperature and frequency ranges. Ceramic capacitors often have relatively low values of capacitance, although higher-value types exist. The construction of these components usually involves metalized ceramic discs, plates or other shapes. These capacitors are generally affordable and offer decent performance for most applications.
