B32522C3684J000 Film Capacitors: Application Field and Working Principle

Film capacitors, also known as plastic film capacitors, are capacitive electronic components with a thin plastic film as its dielectric material. They are characterized by their small size and ability to provide higher capacitance and voltage rating performances than other capacitor types. Specifically, B32522C3684J000 film capacitors, manufactured by the EPCOS, are miniature plastic film capacitors constructed in plastic cases, suitable for use in dry and damp environments.

Application Field

B32522C3684J000 film capacitors are widely used in various types of electrical and electronic equipment, such as television sets, radios, audio devices, and computers. Their small size and superior performance make them suitable for installation in modern consumer electronics. Being widely used in consumer electronics, B32522C3684J000 film capacitors are usually employed in radio, audio and video systems. In radio systems, these film capacitors can be used as bypass, coupling, decoupling, timing, or circuit elements. In audio systems, they can be used for alternatives for electrolytic capacitors, as well as for power supply bypass, RF bypass, and pitch control circuitry. In video equipment, they can be used in power supply applications, as well as for coupling and timing.

Working Principle

A film capacitor’s operation relies on electrical energy that can be stored in a dielectric material. This capacitance is dependent on the thickness, dielectric material, and area of the capacitor plates, and increases with the number of layers of dielectric material between plates. A film capacitor’s dielectric material is a type of plastic, typically polypropylene or polyester.B32522C3684J000 film capacitors are characterized by the fact that they have three more layers of dielectric material than other plastic film capacitors. This gives them a higher capacitance and voltage rating, making them suitable for use in power supplies and in other applications that require high-voltage performance.In terms of construction, film capacitors use metalized or solid metal as electrodes and plastic films as dielectric materials. The metalized films are constructed by depositing a metal layer on the plastic film surface, while the solid metal films do not require any deposition of metal layers but only selecting the right plastic material itself. Depending on the application, these film capacitors can also be constructed in a round or square-shaped design. They are typically hermetically sealed in plastic cases which are filled with a dry air or solid insulation material to ensure stability in operation.

Conclusion

B32522C3684J000 film capacitors provide high capacitance and voltage ratings, making ideal for power supply applications, in radio, audio and video systems. In terms of construction, these film capacitors use metalized or solid metal as electrodes and hermetically sealed in plastic cases, with a dry air or solid insulation material filling the cases. With their superior performance and small size, these film capacitors are perfect for installation in modern consumer electronics.
