Film Capacitors

A film capacitor is a type of capacitor that uses a plastic film as its dielectric material. It is used in a variety of electronic applications, including buck converters, DC power supplies, and certain audio circuits. The CB047G0683KBC is a type of film capacitor specifically designed for high-reliability applications such as aerospace, defense, and medical markets.

CB047G0683KBC Application Field

The CB047G0683KBC is a radial-leaded film capacitor designed to operate in harsh environments. Its main application is in DC-DC converters, where it is used for filtering and transient protection. Additionally, it is designed to offer high voltage operation and extremely low losses. It has a dielectric constant of 6, and a 9kVDC insulation voltage to provide reliable operation in hostile environments. The CB047G0683KBC operates over temperatures ranging from -55 to +125°C, making it an ideal choice for highly mobile applications.

CB047G0683KBC Working Principle

The CB047G0683KBC is a dry film capacitor, meaning that it has no liquid filling. It is built with two plates separated by a dielectric film, usually composed of plastic or Mylar. When voltage is applied to the plate, an electric field develops between the two plates, and electricity is stored in the film. The capacitor can then discharge this stored energy when the voltage is removed from the plates.

The CB047G0683KBC\'s metalized film construction provides numerous advantages over traditional electrolytic capacitors. It has a higher capacitance-voltage ratio, meaning that it can store more energy within a given volume. It also has much better temperature and voltage co-efficiency than electrolytic capacitors, meaning that its capacitance remains stable across a wide range of temperatures and voltages. All of these features mean that the CB047G0683KBC can be used in more specialized applications, such as power supplies and filtering circuits, where reliability and performance are of utmost importance.

Conclusion

The CB047G0683KBC is a high-reliability film capacitor designed for harsh environments. Its metalized film construction provides numerous advantages over traditional electrolytic capacitors, such as higher capacitance-voltage ratio, better temperature and voltage co-efficiency, and more reliable operation in hostile environments. These features make the CB047G0683KBC an ideal choice for demanding applications such as power supplies and filtering circuits.
