Film Capacitors

BFC238554273 Application Field and Working Principle

Film capacitors refer to capacitors that use thin plastic film as electrodes and insulating film. The capacitor is characterized by high insulation resistance, high breakdown voltage, low dielectric loss, stability under long-term working conditions, and good self-healing ability. The capacitance value, working temperature range, size and shape of the capacitor can be customized according to customer requirements. Film capacitor products are widely used in power equipment, electronic ballasts, communication boards, air conditioners, washing machines, electric fans, electroacoustic equipment, instruments and accessories.

The BFC238554273 film capacitor is a series of capacitors manufactured in accordance with international standards. Its structure consists of a polyester film as the electrode material and a metallized process as the electrode. After being sealed and treated with rubber or plastic compound, it forms a packaging compound and gives it excellent geometry, heat resistance, moisture resistance and corrosion resistance. The use of patented construction technologies and a multi-level design make BFC238554273 capacitors ideal for demanding and extreme applications.

The working principle of the film capacitor is based on the principle of electrostatic capacitance. When a DC voltage is applied to two metal electrodes, a layer of metal ions will separate from the metal surface and gather near the opposite metal surface, forming a double-layer structure. The area between the two metal layers acts as a dielectric, and the capacitance directly depends on the area of the electrode and the distance between the two electrodes.

For BFC238554273 film capacitors, the distance between the two electrodes (width and length of the film) is strictly controlled to ensure maximum dielectric performance. Its winding structure is very important. The metalized films are spirally wound together to create a winding structure, and the impregnation compound is then applied for moisture and temperature protection. Once the capacitor has been sealed, it undergoes a series of tests, such as proof test, capacitance test, insulation test, salt spray test, etc., to ensure the performance and safety of the capacitor.

In summary, BFC238554273 film capacitors offer superior performance and reliability for extreme and demanding applications. They have excellent electrical and thermal properties and are able to withstand a wide range of temperatures and humidity. The combination of patented technologies and a winding structure ensures superior temperature and moisture resistance, making them ideal for long-term reliability and performance in extreme and demanding applications.
