Film Capacitors

Film capacitors are constructed from a variety of dielectric materials and feature a thin, protective overcoat of Mylar that provides electrical isolation and mechanical protection. A film capacitor\'s dielectric is a thin sheet of polyester film, a type of insulation material, that is heated and then stretched over a mold to form a molded piece. This dielectric material determines the capacitor\'s capacitance and temperature characteristics. It is these qualities that make film capacitors suitable for use in a variety of applications.

BFC247990017 application field and working principle

The BFC247990017 is a film capacitor designed for a wide range of applications, such as power supplies, inverters, motor controls, switching power supplies, LED lighting and general home appliances. The capacitor features a low ESR (Equivalent Series Resistance) and low self-inductance. It is an ideal choice for use in applications where high frequency switching occurs.

The operating principle of a film capacitor is based on the capacitance that is created between the dielectric and the electrodes. The dielectric acts as an insulator, and the electrodes act as a conductor. When a voltage is applied to the electrodes, an electric field is created within the dielectric. This electric field produces an alternating current in the electrodes and causes charge to be stored on either side of the capacitor. This stored charge creates a capacitance that is proportional to the amount of voltage applied to the capacitor.

The BFC247990017 capacitor is designed to provide high-frequency performance and long life reliability. Its high capacitance and low ESR makes it ideal for application in switching power supplies, where high-frequency switching occurs. The capacitor can withstand temperatures from -30°C to +85°C and is UL-listed and RoHS compliant.

The BFC247990017 is the perfect solution for a wide variety of applications that require high frequency switching. Its high capacitance and low ESR make it a great choice for applications that require long life reliability. Its high temperature capability makes it well suited for applications that require operation in extreme temperatures. This capacitor is UL-listed and RoHS compliant, providing safety and peace of mind for any application.
