Film Capacitors

Film capacitors are characterized by their use of an insulating plastic film as the dielectric material. The films may be metallic, such as aluminum, copper or zinc, or formed from nonmetallic materials like polyester, polypropylene or polycarbonate. The film can be treated and metallized with a foil and electrodes applied at each end, providing the capacitor with its resonance function.

BFC247990119 Application Field and Working Principle

The BFC247990119 type of film capacitor offers a major application field with voltage ratings up to 630V and capacitance ratings up to 1μF. They are designed for use in power supplies, motor drives, UPS inverters, lighting, audio, high frequency switching circuits and other critical applications. They are constructed with a polypropylene film and a metallized aluminum-copper-steel-epoxy electrode combination, and feature excellent temperature and environmental stability.

The working principle of a film capacitor is based on the electrostatic generation of an electrical field between two or more closely separated and conductive elements. The capacitor’s dielectric layer acts like a charge separator, generating a potential response difference between the two electrodes. When an alternating current or voltage is applied across the electrodes, the electric field created results in a reactive charge that is stored and then released when the current or voltage is removed.

The BFC247990119 type of film capacitor is manufactured to operate at low frequencies and high temperatures. It has an extended range of temperature ratings ranging from -25°C to +105°C. They also feature extreme humidity resistance and very low electrical losses. This makes them suitable for use in high-frequency applications, where their low electrical losses provide superior stability when compared to other types of capacitors.

Capacitors of this type are also highly reliable, with high dielectric strength. The BFC247990119 is designed to safely withstand voltage and current impedance without any damage. In operation, they provide excellent performance characteristics, such as low ESR values, low total harmonic distortion and high voltage ratings. This enables them to provide superior power conditioning and signal quality.

In summary, film capacitors such as BFC247990119 provide an excellent application field in high voltage circuits, as well as in critical applications requiring high capacitance ratings, extreme temperature ratings and good frequency stability. Their excellent electrical characteristics and reliability make them suitable for use in a wide range of applications.
