Film capacitors, also known as film dielectrics, are capacitors which use plastic film as the dielectric material. The film capacitors frequently used also include polyester (also called pet) polypropylene (also called pp) polystyrene (also called ps) polyethylene napthalate (also called pon) and polyphenylene sulfide (also called pps). BFC238353153 film capacitor is for high application fields and works on the principle of static capacitance.

Film capacitors are miniature, light weight, large capacity, and have high insulation resistance, stable capacitance, and good safety performance. They are widely used in voltage stabilizing circuits, interference suppression, pulse circuits, high frequency circuits, and other occasions.

Basic Definition and Working Principle

BFC238353153 is a Polypropylene (PP) film capacitor. It is a single-layer capacitor with a polypropylene film dielectric. The electrodes are aluminum foil. The capacitance ranges from 0.47μF to 100μF and the rated voltage is 500VDC. The temperature coefficient is within the range of +200 ppm/℃ to -800 ppm/℃.

The working principle of a film capacitor is based on static capacitance. A capacitor is made of an insulating material between two conducting materials. An electric field is placed between two conducting materials, and it stores electrical energy because the electric field can attract charges from one side and repel them on the other. A thin insulating dielectric material is placed between two conducting materials, and it creates a phenomenon called static capacitance.

In a film capacitor, the polypropylene film serves as the dielectric material, while the aluminum foil serves as the two conducting materials. When a voltage is applied to the capacitor, an electric field is created which causes a separation of electric charges between the two conducting materials. This separation of charges produces an electric field which stores electrical energy.
