Film Capacitors

Film capacitors are nonpolarized components, that are also known as film dielectrics or simply plastic capacitors. Film capacitors have a wide range of applications, and due to their polarization independent design they can handle voltage and pulses from both sides of the power supply. The MKP385410040JF02W0 capacitors are one of the most common types in film capacitors and have a variety of uses including high-frequency applications.

Application Field and Working Principle of MKP385410040JF02W0 capacitors

The MKP385410040JF02W0 capacitors are ideal for applications that require high frequency operation as they have excellent dielectric properties and low ESR. With their use of metallized polypropylene film dielectric, they are able to have an exceptionally low loss, making them have a much higher capacity than other types of capacitors.

Their application could be within many devices such as signal filtering, power factor correction as well as in motors and lighting fields. Power factor correction needs the capacitors to be installed in parallel to the AC power source to decrease the incoming current phase shift.

The working principle of the MKP385410040JF02W0 capacitors is quite simple and is mainly based on the dielectric properties of the plastic film. When a given voltage is applied across the two metal plates, a dielectric field is formed and the capacitance of the film is the main component which determines the capacitance ratio of the capacitor. As the voltage applied increases, the capacitance will increase as well, until the maximum capacitance is reached. When the voltage is then reduced again, the capacitance of the film decreases and hence the capacitance of the capacitor decreases.

The MKP385410040JF02W0 capacitors have a high clarity, good insulation, low dissipation factor and low leakage. They have very long life cycles and can operate in a variety of environmental conditions, making them a reliable choice in a range of applications. They can be very common in equipment and require minimum space and utmost reliability.
