Film Capacitors

Introduction

Film capacitors, also known as film dielectric capacitors, are capacitors with a thin film dielectric. Film capacitors are used in many applications where the reliability and stability of the electrical circuit is of utmost importance, such as medical devices, electronic and aerospace applications. Films capacitors are characterized by an extremely low loss factor, little varying capacitors, wide operating temperature range, good self-healing function and a wide frequency range.Film capacitors are divided into two distinct categories: film capacitors with aluminum metalized electrodes and film capacitors with silver metallized electrodes. Both types provide good electrical properties.The BFC238561622 is a type of film capacitor with silver metallized electrodes. This type of capacitor is specifically designed for use in high voltage applications. It has an insulation voltage rating of up to 10,000 VDC, a maximum ripple current of 10A, and a capacitance ranging from 0.01µF to 0.47µF.

Application field

The BFC238561622 film capacitor is ideal for use in high voltage power supplies and communication equipment. It is mainly used as a EMI filter or snubber circuit in high frequency switching power supplies, switching amplifiers, lighting equipment, UPS power, chargers, inverters and other electrical systems. Furthermore, its high voltage insulation and high ripple current capabilities make it suitable for use in high voltage and high current applications.

Working principle

Film capacitors work by using the inherent electrical properties of metallized film electrodes. The thin film of metal is deposited onto a flexible plastic substrate material which acts as an insulator. This insulation layer and the metal film electrodes are then wound together to form a cylindrical capacitor.The structure of the metallized film creates an alternating double layer capacitor, which stores energy in the electric fields that exist between the two metallic layers. This electric field occurs when a voltage is applied across the capacitor, and is responsible for the capacitance of the device. The higher the voltage applied, the higher the capacitance of the film capacitor.

Conclusion

The BFC238561622 film capacitor is a low ESR high voltage component that is ideal for use in high voltage and high current applications due to its high insulation voltage rating and high ripple current capabilities. The low loss factor and wide operating temperature range of these capacitors make them suitable for use in critical applications. Additionally, the metallized film construction of these capacitors makes them very reliable and stable.
