Film Capacitors

Film capacitors, also known as plastic film capacitors, are electronic components used to store electrical energy in a variety of electrical and electronic devices. The most commonly used type of film capacitors is the polypropylene film capacitor, which is a non-polarized capacitor made of polypropylene film. The capacity of this type of capacitor is determined by the size of the film, the thickness of the film, and the dielectric constant of the film. The property of polypropylene film has excellent electrical stability and excellent temperature characteristics, making it an ideal choice for a wide range of applications.

BFC237590142 Application Field and Working Principle

BFC237590142 Film Capacitors are used in a variety of electrical and electronic applications, such as signal filtering, AC line filtering, and voltage stabilization. The BFC237590142 is a polarized aluminum electrolytic capacitor that is capable of withstanding high voltages up to 630V. The value of the capacitance can be adjusted by adjusting the size and thickness of the film, and the capacitance value is indicated by a colored dot in the middle of the capacitor. The working principle of BFC237590142 capacitors is based on the displacement of electrons in the film according to the applied electric field. When a DC voltage is applied to the capacitor, the negative charge on the film accumulates near the negative terminal of the capacitor and the positive charge accumulates near the positive terminal of the capacitor. This charge displacement creates an electric field within the film, which in turn stores electrical energy in the form of an electrical charge. The amount of charge stored in the capacitor is proportional to the applied voltage and the size of the film. When the voltage is removed from the capacitor, the capacitor discharges through the load, releasing the electrical energy stored in the form of current.

Conclusion

BFC237590142 Film Capacitors are widely used in many electronics, due to their excellent electrical and temperature performance. The value of capacitance can be adjusted by changing the size and thickness of the film, and the working principle of the capacitor is based on the displacement of charges in the film. This allows for a wide range of applications, such as signal filtering, AC line filtering, and voltage stabilization.
