BFC238351393 Datasheet/PDFFilm Capacitors
The film capacitor also known as a plastic film capacitor, a film dielectric capacitor, a film capacitor, a polyester capacitor, or an AC capacitor is a capacitor that uses a thin plastic film as the dielectric. It is also sometimes called a polymer film capacitor, poly film capacitor, or a signal capacitor. Film capacitors are mostly used for high voltage, low current applications, providing relatively low inductance, high insulation resistance, and good frequency characteristics. As such, they are perfectly suited for applications ranging from radio circuits and digital signal communication to audio frequency amplification.
BFC 238351393 Application Field and Working Principle
The BFC 238351393, manufactured by Beijing Capacitor Co, Ltd, is a film capacitor specifically designed for use in high voltage, low current applications. It has a wide range of uses in the electronics and radio communication industries, including high voltage and low current impulse applications, and power circuit damping and decoupling. As a high power capacitor, the BFC 238351393 offers excellent temperature stability, a low dissipation factor, and a high insulation resistance. Its low inductance makes it ideal for use in DC power supply and AC circuits.
The working principle of the BFC 238351393 is based on the same principles as all capacitors: electrical energy is stored in the capacitor by means of electrostatic induction. The dielectric material used in modern film capacitors is generally a thin plastic film, such as polypropylene, polyester, or acrylic. When a voltage is applied to the capacitor, an electric field is developed across the dielectric material and this electric field causes electrons to flow within the film. This flow of electrons creates an electric field in the opposite direction which opposes the electric field of the applied voltage. This opposing field is called electrostatic induction and is what creates the electrical energy storage capacity of the capacitor.
The BFC 238351393 is designed to operate in high voltage, low current applications. As such, it features a wide operating temperature range of -55°C to +125°C and is able to withstand high pulse currents up to 20A.
