Film Capacitors

Film capacitors, sometimes referred to as plastic film or dielectric film capacitors, are a type of capacitor that use a film, usually plastic, as the dielectric and are most often used for AC applications. They have low loss and stable capacitance values over a wide range of temperature and frequency conditions making them ideal for many applications.
