Film Capacitors

Film capacitors, or plastic film capacitors, are electrical components for storing electric charge. They are constructed of alternating layers of metal and plastic films, giving them the ability to safely handle much higher voltages as compared to ceramic capacitors. BFC238300914 is one such film capacitor.

BFC238300914 Application Field

The BFC238300914 is a metallized polypropylene film capacitor. It has a very low dissipation factor (DF) of 0.00020, exceptional temperature characteristics, and extended temperature range of -40 to 85/105℃. Due to this, it appears widely in a number of electronics from power supplies to HID electronic ballasts to high power audio amplifier applications. It can even be employed in Class X2 applications requiring T-rated Capacitors.

BFC238300914 Working Principle

Film capacitors utilize the non-conductive nature of the film medium between metallic electrodes for their capacitance. The films are usually either polystyrene or polypropylene depending on the type of capacitor. BFC238300914 uses the polypropylene film. This film is then metallized on both sides with aluminum or zinc. A separator is then placed between the two films and rolled into a cylinder or case which is then sealed with sealants and a terminal. The capacitance is determined by the thickness and area of the two films in the capacitor as well as the type and number of separator layers.

The performance of BFC238300914 is mainly due to the high-quality polypropylene film, and the construction technique which attaches the metal layers on both sides to the film. The other major components that make up this capacitor are its internal and external electrodes as well as the sealing materials and insulators.

Conclusion

In conclusion, BFC238300914 is a film capacitor that is widely used in high power applications. Its low dissipation factor, exceptional temperature response, and extended temperature range make it an ideal choice for these intense electrical workloads. And due to its quality construction technique, it is able to provide a reliable and long-lasting performance.
