Film Capacitors

Film capacitors, or plastic film capacitor, are capacitors manufactured using a dielectric film made from polyester, polycarbonate, polypropylene, polystyrene, or other dielectric material. An electrical charge is stored in the dielectric material, and this charge creates a capacitor. Film capacitors are commonly used for coupling, decoupling, bypass and energy storage applications. They can also be used as filters and motor starters.

Working Principle

The working principle of a film capacitor is based on the principle of the Faraday effect. A charge is stored on the dielectric material, which is composed of polyester, polycarbonate, polypropylene, or another dielectric material. The charge stored on the dielectric creates a capacitor, meaning the capacitor has the ability to store electrical charge. The stored charge creates an electrostatic field between the two conducting surfaces of the capacitor. This electrostatic field creates a capacitance.

In order to achieve the desired electrical characteristics, the dielectric film of the SFD66S25K391B-F Film Capacitor is made from a specific combination of polypropylene fibers. This combination allows the device to have a very low ESR, low capacitance, and no voltage coefficient. The capacitor also features an electrostatic shield which helps to maintain excellent capacitance stability and enables the device to hold up under extreme conditions.

Conclusion

The SFD66S25K391B-F Film Capacitor is a 25 kVAR radial leaded, polypropylene film capacitor designed for applications that require high current or high voltages. This device can be used in a wide range of applications including electric vehicle powertrain systems, inverters, uninterruptible power supplies (UPS), DC-DC converters, LED drivers, coupling capacitors, motor starters, and filter capacitors. The working principle of a film capacitor is based on the Faraday effect, whereby electrical charge is stored in a dielectric material, which then creates a capacitor to store electrical charge.
