BFC237021823

Background Information

BFC237021823 is a film capacitor, sometimes called a polyester or PET capacitor. Unlike electrolytic and ceramic capacitors, film capacitors are made from thin layers of plastic film that are roll-coated with a metal ( typically aluminum, but occasionally zinc or other metals ) layer. Film capacitors have several advantages over other types of capacitors.

Application Fields

Film capacitors are widely used in automotive, industrial, and consumer electronic applications. Commonly referred to as a "film capacitor," these capacitors are used for various signal processing, filtering, and power supply functions. In the automotive industry, film capacitors are used in alternators, starter motors, and other components. In industrial applications, they are used in high voltage power supplies and lighting ballasts. They are also used in consumer electronics, such as televisions, stereos, and computers.

Working Principles

Film capacitors work through a process called dielectric absorption. This is when an electrical field forms between a pair of capacitor plates and causes they dielectric material ( the plastic film ) to become temporarily charged. The charge then remains in the capacitor until it is discharged. The dielectric absorption process makes film capacitors more efficient than other capacitors for tasks that require filtering or signal processing.

Conclusion

In conclusion, BFC237021823 is a film capacitor with many advantages over other types of capacitors. They are widely used in many industries, including automotive, industrial, and consumer electronics, for their high efficiency and dielectric absorption.
