Film Capacitors

BFC237179223 Application Field and Working Principle

Film capacitors, also known as polymer capacitors, are components that are constructed of thin layers of insulating material such as an aluminum oxide, polystyrene, and polyethylene. They are typically constructed with an anode and a cathode and a dielectric layer. The film prevents electrons from passing through the dielectric, thus forming a capacitor. The BFC237179223 is a film capacitor designed for applications such as audio-frequency filters, switching power supply output chokes and filters, DC blocking and bypassing. These devices can operate over a wide temperature range, from -40°C to 85°C, and are available in a wide range of values. The working principle of a film capacitor is simple. When a voltage is applied to the device, the voltage causes an attraction between the anode and the cathode. This attraction causes a build-up of electrons on the surface of the anode and cathode. As the voltage is increased, the electrons on the surface of the anode and cathode become denser. This denser electron population leads to an increased attraction between the anode and cathode. This increased attraction leads to an increase in capacitance. The BFC237179223 has an effective capacitance range of 0.1µF to 47µF and a maximum voltage rating of 500V. Its operating temperature range is -40°C to 85°C. The device features low ESR (equivalent series resistance) and high Q (quality factor) values for high performance in audio frequency filters and high efficiency in output chokes. In addition, the BFC237179223 is equipped with an electrostatic discharge (ESD) protection system and a fail-safe circuit. The ESD protection system allows the device to operate in an environment with high ESD voltages, while the fail-safe circuit prevents the device from malfunctioning due to failure of the dielectric. The BFC237179223 is designed to provide superior performance in a wide range of applications, from audio frequency filters to output chokes and bypassing. Its wide operating temperature range and its robust ESD and fail-safe circuits allow it to be used in a variety of environments. The device also offers superior capacitance and low ESR, making it a highly reliable and efficient choice for applications requiring a robust capacitor.
