Working principle

B81141C1154M000 is a metalized polyester film capacitor in which two metal electrodes are deposited on both sides of the pet film with metal-plated layers. When power is supplied to the capacitor, electric field is build up on both sides of conductor. These electric fields attract electrons to the metalized electrodes and repel them away. This will create a potential difference between the two electrodes of the capacitor. The electric field accumulates the electric charge in an insulating medium, which is the dielectric. The amount of accumulated electric charge across the dielectric is proportional to the supply voltage.
