Film Capacitors

Film capacitors are components that use layers of plastic film, such as polyethylene terephthalate (PET) or polycarbonate (PC), as a dielectric between two conductive plates. Film capacitors offer a unique combination of stable capacitance and voltage within a small size, and are often chosen for use in small, low-noise analog circuits or in high-frequency switching power supplies. The BFC233867822 capacitor is a widely used, inexpensive film capacitor suitable for a variety of applications.

BFC233867822 Application Field and Working Principle

The BFC233867822 film capacitor is a typically cylindrical component about 3 mm in diameter with a total length of 8 mm. The case is made of enameled aluminum, which makes it robust and relatively heat resistant. As a result, this capacitor is suitable for a range of temperatures from -40 to +105°C and can be used in industrial or automotive environments. This capacitor also features a long life cycle and high current handling capabilities, making it useful in audio equipment and power supplies.

The working principle of the BFC233867822 is based on the use of two layers of thin plastic films as a dielectric between two conductive plates. The dielectric material used in this capacitor is polyester, allowing it to withstand high voltages without losing its electrical characteristics over time. The capacitor also includes a shielding layer between the two plastic films, which ensures that electric signals do not pass between the terminals. This reduces the amount of noise in the circuit, making it suitable for low-noise analog designs.

This capacitor is also available in a variety of voltage ratings, capacitance values, and sizes. It is usually available in ratings from 4V to 400V, capacitance from 0.1µF to 1µF, and typical sizes from 8 to 20mm in diameter.
