Film Capacitors

Film capacitors, also known as plastic film capacitors, plastic film dielectric capacitors, are composed of thin plastic film as dielectric material, aluminum foil as electrode and paper foil as the outer layer of electrodes. BFC233864474 is one of the common film capacitor with two terminals in the market, which is often used as components of electronics equipment and sold in high-volume quantities and in very small packages. It is characterized by high insulation resistance, low leakage and dielectric loss, and good frequency characteristics.

Application Field

BFC233864474 capacitor is widely used in many fields such as DC electrical energy, circuit protection, AC electrical energy, switching power supply, etc, taken as the variable capacitor, pulse filter, and energy storage device. If combined with resistor and inductor, it can be used in oscillation circuits. It is mainly used in electrical products like simple radio sets, digital cameras, and audio equipment. As one of the most important components of the product, it helps to improve the performance and stability.

Working Principle

The BFC233864474 capacitor consists of two conductors, each of them separated by a thin layer of dielectric material such as paper, plastic, ceramic, nylon or other insulating material. When the capacitor is connected to an electrical source, electrical charge will accumulate at the plate of the capacitor and movement of electrons starts from the positive end of the source to the negative end, resulting in electric current flowing through the capacitor.

The higher the capacitance value of the capacitor, the more current it can absorb from an electrical source and the higher the voltage that the capacitor can handle. The capacitance of the film capacitor is determined by the amount of ink or particles it contains, as well the thickness of the film. The thicker the film, the higher the capacitance value of the film capacitor.

BFC233864474 mainly works in two ways: when an AC source is connected to the capacitor, the capacitor can filter out much of the high frequency components of the signal, leaving only heavier low frequency components to pass through, thus improving the quality of the signal. At the same time, it can also be used as a storage device, which can store the energy released by the AC source and release them in a controlled way.
