Working Principle

The working principle of the MKP18453366361R film capacitor is based on the electric field effect. Essentially, an electric field is generated when there is a voltage applied across the capacitor which causes ions to be attracted from the dielectric to the electrodes. This field attracts and maintains ions on the electrodes, creating a uniform electric field across the dielectric. As a result, an electric current will flow through the capacitor plates in order to establish an equilibrium between the charges.

When the capacitor is running, an alternating current is applied to the capacitor, which from a macroscopic point of view is basically an attraction and repulsion of ions that cause the electric field to increase and decrease. This creates a circumferential current through the electrodes which in turn creates a capacitance. The capacitance of the capacitor is directly proportional to the area of the electrodes, the distance between the electrodes, and the dielectric constant of the material used as the dielectric.

The MKP18453366361R film capacitor is a reliable solution for electrical applications as it has a wide operating temperature range and a high capacitance. Its excellent electrical and mechanical properties make it ideal for use in power electronics and other challenging applications.
