Working Principle of ECQ-E2W225KC

The main purpose of the Film Capacitor is to reduce electrical noise in the circuit. It is a non-polar capacitor which contains two metalized (deposited and electrically conductive) polyester films which are separated by an insulator. These films have a net negative charge, and the negative ions repel each other, causing an electrostatic field between the two films. When an alternating current (AC) is applied to the capacitor, the electrostatic field stores the energy and produces a capacitance, which is measured as farads. The capacitance is determined by the physical gap between the two films, the permittivity of the dielectric (insulating) material, and the area between the films. The capacitance of the ECQ-E2W225KC is 225K Farad.
