Introduction to Film Capacitors

Film capacitors, also known as plastic capacitors, are non-polarized electrical components that are widely used in high frequency applications. They are manufactured by coating plastic film, usually polypropylene film, with metalized electrodes, insulating the surface with thin layers of mylar, and rolling the composite material into cylindrical tubular shapes. This design makes them small in size, light in weight and highly reliable in operation. Film capacitors are available in a variety of dielectrics and ratings, for use in a wide range of applications.

BFC237882223 Application Field and Working Principle

The BFC237882223 is a film capacitor that offers excellent high frequency performance in applications requiring long life and high reliability. The capacitor has a dielectric comprising of a metalized polypropylene film, providing an impedance at high frequencies of up to 50 In. The non-polarized design allows for a high ripple current rating of up to 2.2A RMS. The two-layered dielectric also provides superior volumetric efficiency and a self-healing effect, making the BFC237882223 ideal for use in high voltage applications.

The BFC237882223 capacitor works by forming an electrical bridge between two metalized electrodes on each end of the component. When plugged into a circuit, voltage causes a current to flow through the device, creating a dielectric field between the electrodes. This field acts as a type of reinsurance or insulation, creating an energy reservoir that limits the current and prevents circuit overloads. The energy stored in the capacitor can be released when the current drops, reducing the amount of power that needs to be supplied from the power source.

Conclusion

The BFC237882223 is a high quality film capacitor, designed for use in high voltage applications. Its two-layered polypropylene film dielectric and non-polarized design make it resistant to heat, chemicals, and external factors that might degrade its performance. The capacitor is reliable in operation, allowing for a high ripple current rating of up to 2.2A RMS, making it an important part of any electronic system.
