Film Capacitors

Film capacitors, often referred to as dielectrics, are a type of capacitor that uses a thin, usually polyester film, as the dielectric material and either metallic foil, carbonized columns, or deposited metal electrodes, depending on the desired properties. Film capacitors are preferred for applications that require high frequency, and, due to their good stability and excellent value-for-performance ratio, are used in many amplifiers, converters, power supplies, and other electronic equipment.
