BFC233845154 Application Field and Working Principle

Film capacitors, also known as plastic film capacitors, plastic dielectric capacitors, are a type of capacitor that uses a plastic film as the dielectric and is used in a wide variety of applications. The BFC233845154 film capacitor, specifically, is a non-polarized capacitor and has a wide range of uses in electrical and electronic circuits. This article will discuss the application field and working principle of the BFC233845154 film capacitor.

Application Field

The BFC233845154 film capacitor is a non-polarized capacitor, and therefore it can be used in both AC and DC circuits. It is widely used in television sets, radio sets, AV equipments and switch-mode power supplies. As a non-polarized capacitor, it can also be used in circuits where the polarity of the signal is reversed, for example in circuits where an alternating current reverses direction. The BFC233845154 is especially suitable for circuit applications requiring non-polarized capacitors, such as in audio crossover networks and a few other circuits.

Working Principle

The working principle of the BFC233845154 film capacitor is based on the fact that it is non-polarized. This means that it can be connected in either direction with no effect on the capacitor\'s performance. The two electrodes of a film capacitor are separated by a thin plastic film, usually polyester plastic. The plastic film acts as the dielectric, and is responsible for the capacitor\'s ability to store energy. When a voltage is applied to a film capacitor, the electric field generated between the two electrodes causes the dielectric to become polarized. This polarization of the PE film stores electrical energy, making the capacitor act like an energy source.

In addition to the PE film, the BFC233845154 also includes a coating over the electrodes. The coating prevents the electric current from leaking across the electrodes and shorting out the capacitor. The coating also helps protect the capacitor from moisture and other environmental elements. The combination of the PE film and the coating give the BFC233845154 film capacitor a long life expectancy and high reliability.

Conclusion

The BFC233845154 film capacitor is a non-polarized capacitor and can be used in a wide variety of applications. Its working principle is based on the fact that it is non-polarized, and it utilizes a thin PE film as the dielectric. The BFC233845154 also includes a coating over its electrodes to prevent electric current leakage, and ensure a long life expectancy.
