Introduction

Film capacitors, the name suggests, are capacitors in which the dielectric consists of a thin plastic film. These are called as film capacitors because common polyester film is used as their dielectric. Such capacitors can be divided into two major types, Metallized film capacitors and Non Metallized film capacitors based on their construction.

BFC238581621 application field and working principle

BFC238581621 is a non metallized film capacitor that comes with a metal glaze coating over the surface of the dielectric film. The working principle of such capacitors is quite Fickled, It is based on the electrolytic deposition of metal particles on the surface of the film which increases conductivity and provides a high capacitive charge. This makes such capacitors ideal for electronics and audio applications.

Application fields

BFC238581621 is widely used in various electronic and audio applications due to its high capacitive charge. Its main applications include decoupling, bypassing and power line filtering. It can also be used for blocking or storing of electrical power in power supply systems. In terms of Audio applications, its mainly used for speakers and loudspeakers, tone transducers, equalizers, amplifiers and other audio applications.

Working principle

The working principle of BFC238581621 is based on the charge stored in its dielectric thin plastic film. The charge is stored in the film due to the electrostatic attraction between the two electrodes, which when a voltage is applied, creates an electric field in the film. The metal glaze coating on the surface of the dielectric film increases the conductivity and thus the charge stored by the capacitor is increased.

Conclusion

Film capacitors, particularly BFC238581621, are widely used in various electronic and audio applications. Their working principle is based on the charge stored in the dielectric, which is increased by the metal glaze coating on the surface of the dielectric film. This makes them ideal for applications such as decoupling, bypassing, power line filtering and audio applications.
