Film Capacitors

Film capacitors, sometimes called plastic film capacitors, are made with thin plastic films, such as polyethylene, polypropylene, and polystyrene, as their insulation. Film capacitors have low capacitances, typically in the range of 0.1 microfarads (μF) to 1.0 microfarad. The B32537B8684K is a special type of film capacitor and one of the most common.

Application Field

The B32537B8684K is a film capacitor which offers excellent temperature stability and an extremely low leakage current. It is commonly used in audio applications, such as audio power amplifiers, preamplifiers or loudspeakers, and in control and signal conditioning circuits. It is also used in power distribution and renewable energy systems, automotive electronics applications, such as electronic control systems, engine ignition systems, and electric power steering systems.

Working Principle

The B32537B8684K is a film capacitor which works by storing electrical energy as a static electric field on two electrically conductive surfaces that are separated by an insulating dielectric. When a voltage is applied across these two surfaces the electric field is developed, which causes a current flow through the capacitor. The capacitance of a film capacitor is inversely proportional to the thickness of the dielectric, so thicker dielectrics are used to increase the working voltage and reduce the dissipation factor. The B32537B8684K is rated for a working voltage of 400 V AC (or 270 V DC) and has a dissipation factor of 0.2%.

Conclusion

The B32537B8684K is a type of film capacitor which offers reliable performance under extreme temperature and voltage conditions. It is used in a variety of applications, such as audio power amplifiers, preamplifiers or loudspeakers, and power distribution and renewable energy systems. Its low leakage current and excellent temperature stability make it an ideal choice for a variety of electronic applications.
