The product provides stable temperature characteristics, has a low ESR, and is available in expanded tolerance versions.

Working Principle

The basic idea behind a film capacitor is simple. It consists of two conductive surfaces that are insulated from each other. An electrical charge will accumulate on the plates of the capacitor as current passes through them. The plates are separated by a dielectric material which prevents the current from crossing the gap between the plates. The dielectric material used in the capacitor is usually a polymer film due to its high dielectric strength and low conductivity.
