BFC238602564

Film Capacitors

Film capacitors, like their name implies, are capacitors that use a film to function as the insulating medium between two conductive plates. They come in a variety of configurations depending on the type and application needed. One of the most popular configurations is the BFC238602564. This particular capacitor is designed for high current, low voltage applications and utilizes a measure of plasticized polypropylene film (or PEN/PET).

Application Field

The most common application for the BFC238602564 is in small power supplies for switching regulators and charge controllers. It is also widely used in medical equipment, automotive electronics, LED lighting, aerial photography systems and a variety of other types of electronics.

Working Principle

A film capacitor works by utilizing the relative permittivity of plasticized polypropylene to build up electrical charge. When voltage is applied between the two conductive plates, electrons are attracted to the positive plate and repelled from the negative plate. As these electrons build up on the electrodes, they create an internal electric field. This electric field stores energy and allows the capacitor to retain charge even after the power source is removed.

The BFC238602564 capacitor is designed to handle currents up to 25A and provides a low dissipation factor of 0.8%. It is also temperature stable in temperatures up to 105°C, making it a great choice for switching regulators and charge controllers in high temperature environments. The design also allows for a wide temperature range of -40°C to 125°C, and has a variety of alternative configurations to fit different application needs.

In summary, the BFC238602564 film capacitor is used for high current, low voltage applications such as switching regulators and charge controllers. It utilizes a measure of plasticized polypropylene film, allowing it to store electrical charge even after the power source is removed. With its high current capabilities and wide temperature range, it is an ideal choice for many types of electronics.
