Working Principle

A film capacitor, such as ECQ-B1H151KF3, works on the principle of storing energy in a dielectric material. It consists of two electrodes, one positive and one negative, separated by an insulating layer called a dielectric. When an electric field is applied across the two electrodes, the electric field causes ions to migrate across the dielectric and be stored in the capacitor’s electric field. As a result, a voltage is applied across the two electrodes, allowing the capacitor to store energy. The amount of energy stored is proportional to the value of the electric field.

The ECQ-B1H151KF3 film capacitor is also designed to provide a high level of reliability and temperature stability over a wide temperature range. It uses a polyester film as the dielectric material, which provides excellent insulation properties and long-term stability.
