Film Capacitors

Film capacitors are precision electrical components, which are developed for applications requiring higher reliability than that of ceramic, paper, and plastic film capacitors. They are typically used in situations where power or signal filtering, related to temperature, voltage or frequency stability is required. Such applications include audio-frequency noise suppression, high pulse capacity, high voltage power supplies, snubbers, motors, lightning arrestors, and suppression of high power transients. Film capacitors have been around for a long time, and has more recently become more prevalent due to their evolution over time.
