Film Capacitors

Film capacitors, also known as metallized film capacitors, have metalized deposits on an inert film substrate material. This substrate material can be polypropylene, polyester, Teflon and many other film substrates, which are produced by winding, layering and compression methods. The metalized deposits, often composed of aluminum or Zinc, are applied over the substrate material to form the capacitor electrodes.

The BFC237934914 film capacitor is a specialized type of film capacitor that is designed for use in high frequency applications, such as radio frequency antennas, high speed motors, and other applications that involve electronic signals. The BFC237934914 is a shielded film capacitor that is constructed using a non-polarized polyester film substrate, and is designed for surface-mount applications.

Application Field

The BFC237934914 is able to operate in a wide range of temperature ranges, from -55°C to +85°C, making it suitable for some demanding industrial and automotive applications. The capacitor offers a high voltage rating of 85V and is able to handle high voltage surges with a high dissipation coefficient of 17. The capacitor is also resistant to corrosion and is RoHS compliant.

The BFC237934914 is ideal for high frequency applications that require low loss performance, such as antenna or amplifier circuitry. The shielded design prevents the buildup of electromagnetic interference, which helps to maintain an efficient signal path. Additionally, the capacitor is able to handle high-kV power, making it suitable for industrial motor control applications.

Working Principle

The film capacitor works by storing charge in an electric field between two narrow strips of metalized film. Charge is deposited on the metalized film when an AC voltage is applied to the capacitor. The metalized film works to conduct the charge, while the dielectric material between the two films prevents the charge from dissipating. When the capacitor is under load, the charges stored in the electric field between the two metalized films are released in order to meet the demands of the load.

The BFC237934914 capacitor also uses low loss dielectric technology, which allows for the capacitor to operate at higher frequencies, with less power loss. Additionally, the non-polarized design ensures that charge only flows through the capacitor in one direction, eliminating the need for a polarity protection circuit.

The BFC237934914 film capacitor is a reliable and efficient capacitor, designed for use in a wide range of electronic applications. The capacitor\'s shielded design prevents the buildup of electromagnetic interference, while the low loss dielectric technology allows for it to operate at higher frequencies with less power loss.
