Film Capacitors

Film capacitors are widely used in various fields, from audio to industrial. Among them, BFC247990026 is a kind of capacitor with high-end performance. It adopts an environmental friendly and high temperature resistant metal film to wrap the electrodes, which are made of hydrophobic film. Through this design, BFC247990026 can bear temperature as high as 140°C and almost no aging.

Application

BFC247990026\'s excellent electrical properties makes it usable in many fields. Its very low dielectric loss, outstanding insulation properties and large capacity make it suitable for high-frequency, high-end audio equipment, automotive electronics, and variable frequency drives. In addition, the excellent self-healing property of the film capacitor ensures long life no matter what the circumstances.

Working Principle

The working principle of film capacitors is based on the principle of capacitance. A capacitor consists of two electrodes of different polarity separated by an insulating material. When a voltage is applied across the two electrodes, the electric field generated between them will cause electric charges to accumulate on the surface of the insulating material and form capacitance. According to the material and technology used, the resulting capacitance will be different.

The metal film used in BFC247990026 is highly resistive to heat, and the hydrophobic film used on the surface of the electrodes can increase the insulation level of the whole structure. In the case of a long-term voltage, the surface of the electrode material with hydrophobic film will not be corroded by the electric field, so that the capacitance value can be maintained for a long time.
