Working Principle of 225MPW400K film capacitor

Film capacitor is a type of capacitor comprised of plastic film as the dielectric material, with metallic electrodes deposited on the surfaces of each side of the film. The 225MPW400K is made of polypropylene film as the dielectric, with aluminum foils bonded onto both sides of the film. This aluminum foil gives the capacitor higher performance in terms of temperature stability and voltage performance compared to other capacitors. The deposited metal electrode increases the area on which the capacitor acts, which increases the capacitance and decreases the equivalent series resistance (ESR) and equivalent series inductance (ESL).

The 225MPW400K also features a high ripple current capacity which allows for increased current draw from the capacitor for higher power applications. This also makes it a good choice for most power semiconductor circuitry and switch mode power supplies. The capacitance range is between 0.1uF to 0.015uF, which makes this device suitable for wide range of applications.
