Film Capacitors

Film capacitors are solid, miniature capacitors that use an organic film such as polyethylene terephthalate (PET) on its surface. This type of capacitor is used in a wide variety of applications from device power conditioning to RF shielding. Specifically, the MKT1822210104 film capacitor is designed for high-frequency use for high-current applications such as power supply circuits, motors and automotive applications.

Application Field

The MKT1822210104 film capacitor has a range of applications because of its special properties. It is an ideal choice for motor starting and as protection components for power conditioning and conversion applications. It is also used to suppress noise in computers, inverters, switched-mode power supplies and motor-driven equipment. As it has particularly superb heat resistance and vibration resistance, the MKT1822210104 is suitable for automotive applications as well.

Working Principle

The working principle of the MKT1822210104 specifications is determined by the size of the capacitor’s electrode plates and the dielectric material or film that sits in between them. The greater the distance between the plates and the higher the dielectric constant of the material, the more capacitance is created. The unit of capacitance is measured in Farad and is the ratio between charge and voltage.

The working principle of a film capacitor can be studied by looking at the equivalent capacitor circuit. It consists of two plates (electrodes) with a dielectric film between them and layers of insulation on both sides of the film. When a voltage is applied across the plates, the dielectric material becomes polarized and it supports an electric field between them. This electric field is responsible for generating capacitance. The MKT1822210104 film capacitor also features extra shielding layers and protection mechanisms to ensure reliable operation.

The MKT1822210104 film capacitor is an ideal choice for applications that require high-frequency, high-current capability. Its robust construction allows it to tolerate extreme operating conditions, making it an ideal choice for any power conditioning, RF shielding and circuit protection applications.
