Film Capacitors

Film capacitors refer to capacitors consisting of metal films, plastic films, and electrolyte materials. The metal films can be made of aluminum, tantalum, formvar, nickel-cobalt alloy and so on. The plastic films can be made of polypropylene film and polyester film. The electrolyte is usually made of aluminum oxide, tantalum pentoxide, polycarbonate or epoxy resin. Film capacitors are manufactured by winding metal films and plastic films, and impregnating electrolyte material.

Working Principle

The working principle of the B25835K1684K7 film capacitor is based on the principles of electrical capacitance. When AC or DC voltage is applied to the capacitor, the electric field is generated between the film and the electrode. This electric field stores electrical energy, which is equal to the area of the electric field multiplied by the capacitance of the capacitor. When the voltage is removed, the electrical energy stored in the electric field is released, thus allowing the capacitor to function as a storage device.

In addition, the B25835K1684K7 film capacitor has lower dielectric losses than other types of film capacitors. As a result, it can provide improved performance and reliability in high voltage applications. It also has excellent temperature and frequency characteristics, as well as low resonance impedance.
