Working Principle

A film capacitor is an electrical component with two electrical conductors separated by a dielectric material. The conductors are typically made of aluminum or copper foil. The two conductors form an electrical circuit; when a voltage is applied to them, an electric field forms, which causes charge accumulation on the conductor’s surface. This charge, combined with the dielectric material between them, creates an electric field, which determines the electrical properties of the capacitor.
