Working Principle

The working principle of MKP1839122634 film capacitor is based on the fact that a dielectric material can be polarized when an electric field is applied across it. As the electric field is applied, the dielectric material polarizes, accumulating a certain amount of charge. This charge is known as capacitance. The amount of charge stored by a dielectric material is proportional to the applied electric field.

The MKP1839122634 film capacitor has two metal electrodes, which act as the charge carriers for the capacitor. When a voltage is applied to the electrodes, the metal electrodes accumulate charge, creating a positive and negative pole on each electrode. As current passes through the capacitor, the capacitance increases, storing energy. When the voltage is removed, the charge carriers dissipate, releasing the stored energy.

The MKP1839122634 film capacitor has a wide temperature range of operation, enabling it to maintain its electrical properties over varying climates. Its high insulation resistance ensures signal integrity in applications such as audio/video and telecom, and its low dielectric absorption helps keep distortion at a minimum level in switching mode power supplies. Its high stability over temperature and time makes it a reliable choice for many applications.
