Working Principle

The DPFF8S22J-F Film Capacitor is an electrolytic capacitor that features a thin film of polypropylene that is dielectric material with excellent electrical insulation properties. This thin film produces a high dielectric constant that is stable over a wide range of temperatures and frequencies. This high dielectric constant allows the capacitor to achieve a high-energy density and low levels of self-induced noise. The high-quality, tightly wound and tightly connected copper foil electrodes ensure excellent electrical connection and high capacitance.

The basic working of a Film Capacitor is as follows: the thin Polypropylene Film and the metallic foil electrode sandwich form a capacitor. When a voltage is applied across the capacitor, a current flows, charging or discharging the capacitor. The capacitor stores energy and the amount of energy stored depends on the charge and the capacitance. The current flow alternates with the applied voltage, and the energy stored in the capacitor is dissipated into the external circuit.

Film Capacitors have an advantage over conventional capacitors in that they can store higher levels of energy in a smaller package. Their high working voltage and dielectric stability over various temperatures makes them suitable for use in a variety of applications, including power electronics, DC power supplies, and switching power supplies.
