Film Capacitors

BFC237678203 application field and working principle

Film capacitors are also known as polyester capacitors, Mylar capacitors or plastic film capacitors. They are non-polarized capacitors with a wide variety of usage scenarios and a long lifespan even under extreme working conditions. BFC237678203 capacitors are a type of film capacitor whose applications and working principle will be discussed in this article.

Application Field

BFC237678203 capacitors have solid dielectric insulation and the capability of withstanding a large temperature range from -40°C to +105°C. Thus, these types of capacitors can be used in situations where other capacitors would break down when exposed to extreme temperatures. In addition, these capacitors can be rated for both AC and DC, allowing them to be used for AC cycle-by-cycle sorting and ripple current tests in motors and power supplies, as well as AC interference suppression in communication circuits.

BFC237678203 capacitors are also used in a variety of industrial applications including medical equipment, security systems, industrial automation systems, auto electronics, and LED vector series. Furthermore, these capacitors are often used in electro chemical equipments and measuring and controlling systems due to their compatibilities with a variety of power sources.

Working Principle

The BFC237678203 capacitor is made up of a metalized film as the material for the metallized layer. These metalized films are a thin polyester film coated with an incredibly thin layer of metal oxide. This layer of metal oxide provides a high degree of stability and long-term reliable performance. Once the metalized film has been prepared, it is then wound up onto an aluminum electrode and held in place by two separate insulators.

The dielectric used in the BFC237678203 capacitor is an ultra-thin polymer film which helps to prevent leakage and holds up against overvoltages. The large storage capacity and high dielectric strength of the capacitor make it suitable for use in applications requiring high power dissipation and greater energy storage. The aluminum electrode of the capacitor helps reduce the RF interference and enhance the EMC performance of the entire system.

In its operation, the capacitor acts as a two-terminal electrical device, meaning that it stores electrical charge in the form of an electrostatic field between two electrical conductors. The electric charge moves between the capacitor’s terminals due to the applied voltage, and this movement of charge produces a charge storage capability. This built-up charge is stored until the capacitor is discharged, during which time the stored energy is released as electricity.

Conclusion

BFC237678203 capacitors, used for their excellent heat resistance and voltage tolerance, are widely applied in a large variety of industrial products. The ultra-thin polymer dielectric helps reduce energy leakage and makes for insulated operation while the aluminum electrode helps reduce RF interference and improves EMC performance. Thus, the BFC237678203 capacitor can be a reliable and efficient partner for any industrial application.
