Film Capacitors

BFC236845105 application field and working principle

A Film Capacitor is an electronic device consisting of two flexible films coated with metal electrodes. Film Capacitors are used for high frequency and high temperature applications. As its name implies, a Film Capacitor is constructed from two dielectric films made of polymer or paper with metal electrodes on the surface. It offers some characteristics greater than other types of capacitors such as high insulation resistance, high voltage rating, large capacitance values, low distortion, and wide range of application. This type of capacitor is mainly used to filter signals, reduce impedance, and maintain a capacitor of constant value in oscillatory circuits.

The construction of a Film Capacitor is simple and consists of two flexible films coated with metal electrodes. The films are usually made of paper or polymer and plate or impregnated with metal particles. The two films are placed on either side of a spacer material which separates the films and provides an electrical insulating barrier. The two electrodes also function as electrical contacts that allow the capacitor to be connected to a circuit. The dielectric film is based on a polymer or film dielectric material and acts as a insulating barrier between the capacitor plates. The capacitance of the capacitor is dependent on the thickness and composition of the dielectric material. Some common dielectrics used in film capacitors are polyethylene terephthalate (PET), polycarbonate (PC), and polystyrene (PS).

The working principle of a Film Capacitor is based on the same fundamental principles as any other capacitor, in that an electric field is created between two plates by the application of an electric potential. As current passes through the capacitor, the electric charge is separated, thus storing an electrical charge. This stored charge produces a field of a specific magnitude and direction, which allows for the smooth flow of electrical current. The capacitance of a Film Capacitor depends on its size and the thickness and composition of the dielectric material. The larger the capacitor, the higher the capacitance. Similarly, the thicker the dielectric material or the higher its dielectric constant, the higher the capacitance.

BFC236845105 is a Film Capacitor with excellent performance and long life. It is suitable for high frequency and high temperature applications and has a wide range of applications. This capacitor has high insulation resistance and can handle high voltage up to 450 VDC. It is also suitable for circuits with high transient voltages and large capacitance values. Due to its low distortion, it is perfect for filtering signals and reducing impedance. Furthermore, it is a non-polar capacitor and can be used in both AC and DC circuits.

The BFC236845105 is an ideal Film Capacitor for many applications. It is commonly used in audio systems, electronic meters, power supplies, and other circuits requiring high frequency and high temperature. This capacitor can also be used in automotive, telecommunications, and medical applications. Additionally, due to its low distortion and wide capacitance values, it is often used in oscillatory circuits, sensors and radios. Its high insulation resistance, high voltage rating, and long life are some of the reasons why this capacitor has become increasingly popular in the electronics industry.
