Film Capacitors

The BFC237541241 is a type of film capacitor, a component used to store electrical energy for a wide variety of applications. Film capacitors have become increasingly popular due to their superior durability, low temperature coefficient, and large maximum capacitance (up to microfarads).

Application Field

Film capacitors are used in a variety of electrical and electronic applications. These include coupling (blocking or bypassing alternating current), energy storage, filtering, and signal isolation. Applications range from consumer electronics, communications, automotive, industrial automation, to military and aerospace.

Working Principle

Film capacitors are constructed from two layers of plastic film separated by a thin layer of an insulating material. A metalized version of these capacitors is also available, where a conductive layer is applied to the internal surface of the plastic film which forms the plates of the capacitor. When a voltage is applied, an electric field is created between the plates, resulting in capacitive reactance, which means capacitors can store electrical energy. Since these capacitors are non-polarized, the polarity of the applied voltage does not affect the performance.
