Film Capacitors

Film capacitors, or plastic film capacitors, are capacitors made from thin film polyester materials. These capacitors are low cost and can be used over a wide temperature range with almost no variation in their electrical characteristics. They can also provide high insulation between their terminals and provide protection against short circuits. These capacitors have gained in popularity due to their low cost and high electrical characteristics.

Working Principle

The MKP1840422405M Film Capacitor works on the principle of electrostatic field. It consists of a dielectric material, such as polypropylene, that is sandwiched between two conducting plates. When a voltage is applied across the plates, an electric field is produced, which induces a charge on the dielectric material. This charge acts as a capacitor plate, storing an electric charge and creating the capacitance. The capacitance of a capacitor is directly proportional to the area of its plates and inversely proportional to the distance between them.

The MKP1840422405M is designed to handle high-current applications, since its low uncontrolled temperature coefficient and wide operating temperature range make it suitable for a variety of applications. Its unique self-healing property ensures that the capacitor does not suffer any damage even if there is an over voltage event. Its low ESR also ensures smooth operation with no spikes in current.
