Film Capacitors

A film capacitor is an electrical component that stores electric energy and acts as an energy source. It is one of the most common type of capacitors, capable of storing a relatively large amount of energy over a wide range of operating temperatures. Film capacitors are divided into organic film capacitor and inorganic film capacitor.

160563K400F-F Application Field and Working Principle

160563K400F-F is an organic film capacitor. It is typically used as a bypass capacitor in circuitry. It is a type of capacitor frequently used in AC and DC applications. It can filter transients, increasing and improving signal-to-noise ratio in audio products.

The film capacitor has two electrodes and the capacitor is filled with an organic dielectric material.
The electric field generated between the two electrodes causes the dielectric material to become polarized, forming an electric dipole that can store electrical energy. The electrodes determine the size of the capacitor and the thickness and dielectric constant of the dielectric layer determine its capacitance. The working principle is very simple, when the voltage applied to the metal electrode is greater than the dielectric strength of the organic film, a dielectric layer will form between the metal electrodes, and an electric dipole will be formed at the same time. It can store electrical energy, so the energy can be transferred from one point to another by the capacitor.
