Film capacitors, also known as plastic film capacitors or polyester/polypropylene film capacitors, are inductive components made of films and plastic films.MKP383420040JFM2B0 film capacitors have low loss and a wide range of working temperature and voltage. They are primarily used for AC/DC filtering or decoupling and coupling applications in many electronic systems.

The MKP383420040JFM2B0 film capacitor is a plastic film capacitor that is designed to operate with an AC/DC voltage of 400V and a maximum capacitance of 0.04µF. This capacitor is available in two different sizes, the 18mm x 13.2mm MKP383420040JFM2B0H and the 16mm x 10.5mm MKP383420040JFM2B0S.The MKP383420040JFM2B0H features an extended temperature range of -40°C to +85°C and an insulation resistance of ≥ 10GΩ. The MKP383420040JFM2B0S has an extended temperature range of -25°C to +85°C and an insulation resistance of ≥ 5GΩ. Both capacitors are lead-free, which make them RoHS compliant.

The working principle of the MKP383420040JFM2B0 film capacitor is based on the dielectric properties of plastic film. A plastic film capacitor uses two metal electrodes separated by a plastic film material. When an electric field is applied to the electrodes, the electrons in the film material create a polarization effect, resulting in a dielectric field. This dielectric field inhibits any current flow between the two electrodes. The electric field in the plastic film capacitor will determine the capacitance of the capacitor, with greater electric fields resulting in higher capacitance values.

As a result, the MKP383420040JFM2B0 is suitable for many different applications, including AC/DC motor drivers, frequency converters, power lines, and medical equipment. The capacitor’s low loss and wide temperature range make it an excellent choice for long-term stability and reliability. Additionally, its lead-free design makes it RoHS compliant and thus environmentally friendly. The MKP383420040JFM2B0 is an ideal choice for a variety of applications because of its superior performance and low cost.
