Film capacitors, also known as plastic-film capacitors, poly-film capacitors, and paper-film capacitors are electronic components that are typically used in power conditioning, voltage coupling, and intermediate signal filtering. BFC238603474 film capacitors are one type of such capacitors that are made from polypropylene materials. It has a superior dielectric strength of 675 volts. This makes it a reliable and robust part in various applications.

Application Fields

BFC238603474 film capacitors have a wide range of uses and applications. They are used as power-line filters for suppressing high-frequency noise caused by switching circuits such as computer circuits and communication circuits. These capacitors are also used in audio-frequency circuits for audio-frequency filtering and in DC/DC converters as smoothing capacitors.

Working Principle

The working principle of these polypropylene film capacitors is based on the ability of this material to store charge. This is due to its dielectric behavior which allows it to store electric charges between two conductors even when an electric field is applied to them. It consists of two conductive plates that are separated by a thin layer of polypropylene. When an electric field is applied, it allows for the flow of electric charge from one plate to the other. The charge stored between the plates helps in providing capacitance. The capacitance of the capacitor is proportional to the electric field and the area of the plates, and is inversely proportional to the distance between them. This dielectric value of polypropylene film makes it a suitable choice for various applications.
