Film capacitors are constructed using multiple sheets, or films, of metal foil creating alternate layers of anelectrically insulating film, typically polyester, and a conductive layer. The two primary componentsof a film capacitor are the electrodes and the dielectric. The electrodes of a film capacitor aretypically aluminum, but can be other metals such as zinc, and are usually deposited onto either thefilm or underlying substrate.

BFC236743563 Application Field and Working Principle

BFC236743563 film capacitors are generally used when a very accurate capacitance value isrequired. The maximum working voltage is up to 63Vdc and the maximum capacitance is up to3.3 μF. This type of film capacitor is commonly used in low voltage, high current applicationssuch as in car audio systems, as a bypass capacitor in power supplies, and many other electroniccircuits.

The working principle of a film capacitor is based on the same principles of conventionalcapacitors. When a voltage is applied across the terminals of the capacitor, a charge is stored on thesurfaces of the plates. This happens due to the dielectric material, which inhibits the flow ofelectrons through the capacitor while still allowing for the charge to pass through. Because of thedielectric material, the capacitor is able to store and release a charge, which can be used to filter andmodulate signals.

BFC236743563 film capacitors are particularly well-suited for applications requiring excellenttemperature stability, long life, and low ESR values. When used in power supplies, they can provideup to 95% of the peak performance which makes them an ideal choice for a range of applications.In addition, they offer excellent ripple rejection for RFI and EMI noise absorption.
