Film Capacitors

Film capacitors are a special class of capacitors that use a plastic or polymer film as a dielectric medium for storing electrical energy as a static electric charge. Unlike electrolytic and ceramic capacitors, film capacitors provide excellent thermal stability, superior voltage ratings, and very low leakage current. Film capacitors are commonly used in signal conditioning, high frequency filtering, AC coupling, and taking advantage of their inherent high-frequency-selectivity.

B32672Z6564J000 Application Field and Working Principle

B32672Z6564J000 is a film capacitor made by Epcos. It is part of the B32672 product series and is capable of handling а 4ЕЗ working voltage. This а low-ESR capacitor is mainly used for bypassing, decoupling, energy storage, and filtering in power supply circuits.

The B32672Z6564J000 has a curved Polypropylene film as the dielectric medium. Polypropylene is an excellent dielectric for use in film capacitors due to its high thermal and electrical stability. The capacitor is also covered with a metallized electrode which is made up of an aluminum evaporated layer to act as the electrode together with a thin protective coating of zinc nitrate. The metallized electrode is then covered by a paper sheet and impregnated with a special oil which also acts as an arc-resistant protection.

The working principle of the B32672Z6564J000 is fairly simple. The electrical charge stored in the capacitor is determined by the capacitor\'s capacitance which is the measure of the amount of electrical capacitance it can store per volt. When a voltage is applied across the leads of the capacitor, the electrodes create an electric field which causes the electrons to move, thus storing energy which can be released when the capacitor is discharged.

Due to its low ESR, the B32672Z6564J000 is ideal for use in power supply circuits and high-frequency applications. Other applications include noise suppression, smoothing, and filtering out unwanted signals from a power supply system.
