Film Capacitors

Film capacitors, also known as plastic film capacitors or film dielectric capacitors, are capacitors with a thin plastic film as the dielectric. They are constructed with two electrodes, each consisting of a thin metal strip or sheet, separated by a thin plastic film dielectric and multiple dielectric layers may be used, depending on the desired capacitance of the capacitor. These capacitors are usually polarized capacitors and are widely used in electronic circuits, due to their superior electrical properties, such as high-frequency characteristics and low ESR.

BFC247964123 Application Field & Working Principle

BFC247964123 is a type of film capacitor with low ESR. It is designed for a wide range of applications, including power supplies, DC-DC converters, switch-mode power supplies (SMPS), and any other circuit with high-frequency signal transmission requirements. It has a wide range of operating temperature ranges, from -40 to +105°C, which makes it suitable for use in harsh environments.

The working principle of BFC247964123 can be described as follows. When electric field is applied between the electrodes, an electric current will flow through the capacitor. The electric current will cause positive charge carriers to accumulate at one electrode, forming an electric field and a negative charge carriers at the opposite electrode. This electric field will generate an electric field that is opposed to the applied electric field. This counteracting electric field causes the capacitance of the capacitor to increase, thus increasing its ability to store electric energy.

The BFC247964123 capacitor is designed with film dielectrics to give it superior electrical and mechanical performance. The dielectric is usually made from various polymeric materials such as Polyester, Polycarbonate, PEN, and PEI. These materials are highly stable, so the capacitance is maintained over a long period of time. The dielectric also provides a high insulation resistance and high insulation voltage rating, which ensures reliable operation even at high frequency.

BFC247964123 capacitors are widely used in power supplies, DC-DC converters, SMPS, and a variety of other circuits. They offer superior electrical properties, including low ESR, high insulation resistance, high insulation voltage rating, and long life. They also have a wide range of operating temperatures, making them suitable for use in harsh environments.
