Film Capacitors

Film capacitors, also known as polyester capacitors, are a type of capacitor that made from an organic film, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or polyphenylene sulfide (PPS). The most common type of film capacitor is the metalized film capacitor. This is usually made of a metalized polypropylene film dielectric, which is sandwiched between two metal electrodes and semi-airtight sealed between a metal case.

BFC238320124 Application Field and Working Principle

BFC238320124 is a metalized film capacitor developed by SCE Technologies and released to the market in 2012. Its main application fields including automotive, aerospace, medical, industrial, and consumer electronics. BFC238320124 is mainly used for voltage and current filtering, such as ESD filtering, precision timing elements, power supply, and RF applications.

Metalized film capacitors can be divided into three parts, the dielectric film, the electrodes, and the case. The dielectric film acts as the core of the capacitor and it is a thin sheet of plastic coated with metal. The metalized film in BFC238320124 uses a dielectric film made of polypropylene, which gives it excellent temperature and frequency stability. The electrodes are two metal plates, one of which is connected to the dielectric film and the other to the case. The electrodes create an electric field within the capacitor which is used to store energy. Finally, the case is used to seal the capacitor and protect it from the environment.

The working principle of a metalized film capacitor is as follows. When a voltage is applied across the electrodes, it causes the electrons in the dielectric film to be repelled away from one electrode and attracted to the other electrode. This causes an electrical charge to accumulate on both electrodes, resulting in an electric field within the capacitor. This electric field stores energy. When the voltage is removed, the electrons are attracted back to their original positions, releasing the stored energy.

In summary, BFC238320124 is a metalized film capacitor developed by SCE Technologies and released to the market in 2012. It is mainly used for voltage and current filtering, such as ESD filtering, precision timing elements, power supply, and RF applications. The metalized film in BFC238320124 uses a dielectric film made of polypropylene, which gives it excellent temperature and frequency stability. The working principle is that when a voltage is applied across the electrodes, it causes an electrical charge to accumulate on both electrodes, resulting in an electric field within the capacitor, which stores energy.
