Introduction to Film Capacitors

Film capacitors belong to the category of non-conventional capacitors, which are also known as dielectric capacitors. They are made from a wide range of dielectric materials, such as polyester, polycarbonate, Mylar, polypropylene, polystyrene, polyethylene terephthalate, polyethylene naphthalate and polysulfone. Film capacitors are known for their stability, low dissipation factor, low inductance, high temperature stability and excellent long-term stability. These characteristics make them ideal for various applications in the electrical and electronic industries.

BFC238371563 Application Field and Working Principle

BFC238371563 is a polypropylene film capacitor and has a maximum rated voltage of 250V. The working principle of this capacitor is based on its dielectric material, referred to as the non-conventional dielectric material. This non-conventional dielectric material is made from layers of polypropylene film, which are encapsulated in a thin metal film.

As the electric current passes through the circuit, the electric field generates, which causes the dielectric material to react to it. The reaction of the dielectric material - as the electric current passes through it -counters the electric field and reduces its magnitude, thereby allowing the capacitor to store an electric charge. This capability of storing an electric charge is used in various applications in different industries, such as automotive, computer, communications, lighting and consumer electronics.

In automotive applications, film capacitors are used in alternators, starters, and subwoofers. They are also used as power-supply filters for engine electrification purposes. In computer applications, film capacitors are used for power supply smoothing and decoupling. They are also used as disk drive filters and electroluminescent backlight inverters. In communications applications, film capacitors are used for electro-magnetic interference (EMI) shielding, RF signal coupling and low-frequency coupling. In lighting applications, film capacitors are used as ballast, transformer, and relay capacitors. Lastly, in consumer electronics applications, film capacitors are used for coupling, diodes, instrumentation and switching.

Conclusion

In conclusion, polypropylene film capacitors such as the BFC238371563 are widely used in various industries for their electrical and electronic applications. They are known for their excellent stability, minimal inductance, low dissipation factor, and high temperature tolerance. The working principle of these capacitors is based on their non-conventional dielectric material, which is made from polypropylene film encapsulated in a thin metal film. This material helps in countering the electric field and allowing the capacitor to store an electric charge.
