Working Principle

The MKP385413125JI02W0 film capacitor works by storing an electrical charge between two thin metalized plastic sheets. It is essentially a two-layer dielectric that is tightly rolled up and encased in a plastic shell. When a voltage is applied across the capacitor plates, an electric field is created. The electric field causes a charge to take shape across the dielectric layer, which creates a storage capacitance. This capacitance can then be used to store electrical energy or filter out unwanted signals.

The MKP385413125JI02W0 capacitor also has a self-healing property. Whenever a breakdown occurs, the surfaces of the metalized plastic film fuse together. This helps to protect the capacitor from further damage. The self-healing property also makes the MKP385413125JI02W0 capacitor suitable for use in safety critical applications where capacitor failure could result in injury or death.
