With regards to the working principle, a film capacitor consists of two thin metallic films separated by a thin insulator. The electrical impedance of a capacitor is determined by the size of the surface area of the two films and the distance between them. When a voltage is applied to the two films, an electric field is created between them, which causes a charge to flow between them. This charge builds up on the two metals plates, which creates a capacitance. The capacitance of the capacitor is a measure of the electrical energy stored in the capacitor.

Finally, when considering the application field of ECQ-E2825JFB, the film capacitor is suitable for applications requiring a high voltage rating.
