Film Capacitors

Film capacitors are a type of capacitor that consists of a thin film of a dielectric material, such as plastic or paper, that is wrapped around two plates of metal. The metal plates act as the two terminals of the capacitor, and the dielectric film acts as a dielectric material, which means it is conductive but not active. The capacitance of the device is dependent on the area of the plates, the dielectric constant of the film, and the thickness of the film.

SFC48T24L391K-F Application Field and Working Principle

The SFC48T24L391K-F is a film capacitor designed for use in industrial and commercial applications. It has a capacitance of 48 μF, a voltage rating of 24 VDC, and a dissipation factor of 0.39%. This type of capacitor is typically used in applications where the voltage is low, the operating temperature is high, and the voltage fluctuates. It can be used in motor run applications, power supplies, and energy storage systems.The working principle for the film capacitor is simple: when an electrical current is applied to the two metal plates, the electric field created by the current causes the dielectric material to polarize and form an electric field in the space between the plates. The dielectric material then acts as an insulator, which prevents the flow of electrons. This creates the electrical capacitance for which the device is designed. The capacitance will increase as the area of the plates and the dielectric constant of the film increase, and decrease as the thickness of the film decreases.

Advantage of SFC48T24L391K-F
