Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor with a film as the dielectric in which the electrons are stored. Film capacitors are one of the most widely used types of capacitors. This type of capacitor is used in a number of applications, including radio frequency circuits, power supplies, and audio/video equipment. In some cases, film capacitors are used as a voltage-dependent component in a DC supply, while in other cases they can be used in an AC-supply circuit.

890334026014CS Application Field and Working Principle

The 890334026014CS film capacitor has a wide range of applications. These capacitors are used in various power supplies, filtering, voltage-dependent and other switching circuits, as well as in the production of radio frequency circuits. These film capacitors offer excellent temperature stability and low-loss characteristic over a broad frequency range. The 890334026014CS film capacitors can also be used for low-loss metallized capacitor elements, such as decoupling capacitors, DC-DC converters, and charge pumps.

The 890334026014CS film capacitor works by storing and releasing electrons in between the two metal electrodes. The dielectric material separates the electrodes. The dielectric material is a film of a plastic material, such as polyethylene or polypropylene. The plastic has a dielectric constant that determines the capacitance of the capacitor. The capacitance is determined by the size and thickness of the electrodes, as well as the material used for the dielectric material.

When a voltage is applied to the capacitor, the electric field between the electrodes sets up an electric current flow called conduction. As the capacitor charges, the electrons move between the electrodes and the capacitor stores the energy. When the voltage is no longer applied, the electrons move back to the electrodes and the capacitor releases the energy. This process is repeated until the capacitor is fully discharged.

The 890334026014CS film capacitor is an extremely reliable and durable device. It is also very efficient, economical and its components are usually easy to obtain. This makes them ideal for a wide range of applications.
