Film Capacitors

Film capacitors, also referred to as plastic film capacitors, are capacitors featuring a plastic film dielectric material, such as polypropylene or polyester. They can be used in a variety of electronic circuits, from low frequency to high frequency, and are considered to be reliable and type-stable. Film capacitors offer high insulation resistance, linear capacitance with temperature, and good temperature stability. The most common film types include polyester, polycarbonate, metallized paper and polypropylene.

The B32520C6472K is an axial film capacitor from Epcos which features polypropylene (PP) as the insulation material. It is a non-polarized, polypropylene film capacitor which features a relatively high resistance and insulation. It is able to operate up to 400V AC/DC at 105 degrees Celsius, and has a maximum capacitance of 0.68µF.

Application Field

The B32520C6472K is designed to be used in various applications, such as snubber, free-wheeling, tuning and line filtering. It is suitable for AC and DC applications in various low-frequency and medium-frequency applications, and is suitable for a wide range of temperatures, from -25°C to +105°C. The capacitor is suitable for operation in damp surroundings, and has a plain anodic coating for easy soldering.

Working Principle

Film capacitors work similar to regular electrolytic capacitors, but with film as the dielectric material instead of electrolyte. When an electric charge is applied to a capacitor\'s plates, an electric field is created that causes a charge to be stored on the plates. This charge will remain stored until a circuit is closed, and the current is allowed to flow between the plates, thereby discharging the stored charge. The dielectric material found in the film capacitors act as the insulating material between the plates, and the more dielectric material found, the higher the stored charge will be.

The construction of B32520C6472K is based on two aluminum foil electrodes with a PP film. The electrodes are connected by an insulated lead that allows a current to flow between the two foils, thus enabling the capacitor to function. The structure of this particular capacitor is designed to be robust and to withstand a variety of temperatures and environments. As such, it is suitable for a broad range of applications.

Conclusion

The B32520C6472K is a popular film capacitor that is suitable for a wide variety of applications. Its construction utilizes a polypropylene film for its dielectric material and the two aluminum foil electrodes with an insulated lead, enabling the capacitors to work in a robust manner. The film capacitor is able to withstand a variety of temperature and environments and is suitable for AC and DC applications in various low-frequency and medium-frequency applications.
