Film Capacitors

Film capacitors are energy storage devices composed of three major components: a dielectric film, external conducting electrodes, and dielectric film insulation. The capacitor usually consists of one or more layers of a dielectric material sandwiched between two sheets of conducting electrodes. This type of capacitor is divided into two categories, implemented either simultaneously or sequentially: moulded film capacitors and metallized film capacitors.

The dielectric material used in film capacitors can be a variety of polymers, such as polyester, polypropylene, polyethylene naphthalate, polyimide, polyvinylidene fluoride (PVDF), styrene, or polyphenylene sulfide (PPS). Dielectric films can be thick or thin, depending on the application. For high-voltage applications, thick dielectrics are used for insulation, while for low-voltage applications, thin dielectrics are used. Additionally, the type of dielectric material also determines the capacitance value.
