Film Capacitors

A film capacitor is a type of capacitor where the electric charge is stored on a plastic film. The film is coated with a conductive material such as aluminum or zinc, and this forms two electrodes that are separated by a dielectric material. The dielectric material used in this type of capacitor is typically paper, polyester, or polypropylene, and this makes them ideal for use in high frequency applications or circuits.

Application Field

The application field of BFC233915183 film capacitors includes a wide range of applications. It can be used in radio and television circuits, computer power supplies, consumer electronics, industrial and medical instrumentation, automotive applications, air-conditioning systems, and other electronic equipment. It can also be used as a general-purpose capacitor in power supplies and power-electronic circuits.

Working Principle

The BFC233915183 film capacitor works on the principle of a capacitor. It essentially stores an electrical charge in a thin plastic dielectric layer between two metal electrodes. As the electric charge is applied to the electrodes, electrons move from one electrode to the other, creating an electric field in the dielectric. This electric field is what stores the energy of the capacitor. When the electric charge is removed from the electrodes, the electric field in the dielectric collapses, and the energy stored in the capacitor is released.

This capacitor is designed with an external metallized film that works well for high frequencies up to 220 kHz. The advantage of this type of capacitor is that it produces very low dielectric absorption, resulting in low losses at high frequencies. It is also very reliable and is capable of handling transient overvoltage without any significant damage.

BFC233915183 film capacitors are designed for long life and superior performance under extreme conditions. The self-healing feature of its dielectric material improves reliability and safety, making it the preferred choice for high frequency applications.
