MKP383322140JI02W0

Film capacitors, also known as plastic film capacitors, are an important category of capacitors that are broadly used in a wide variety of applications. This article will be dedicated to discussing the application field and working principle of MKP383322140JI02W0.

Film capacitors are made up of a capacitor element that is laminated with a dielectric material between two metal (aluminum or zinc) electrodes. The type of dielectric material used would influence the characteristics of the ensuing capacitor. For MKP383322140JI02W0, the dielectric material used is polypropylene film, which gives the capacitor the advantages of excellent self-healing properties, excellent temperature characteristics, free of maintenance, and high surge current intensity.

Application Field

MKP383322140JI02W0 is a great choice for general purpose applications. Its excellent frequency characteristics make it suitable for power supplies, power supply filters, and inverters. The high temperature and voltage rating of MKP383322140JI02W0 make it well-suited for high-power applications such as motor drives, air conditioners, and power factor correction. It is also ideal for other electrical and electronics applications such as radio frequency (RF) circuits, audio filters, digital circuits, and timing circuits, among others.

Working Principle

The working principle of MKP383322140JI02W0 is the same as that of other film capacitors. It utilizes the dielectric material between two metal plates to store electrostatic energy in an electric field. The dielectric material used in MKP383322140JI02W0 is polypropylene film.

When a DC voltage is applied to the electrodes on either side of the dielectric film, the electrostatic field collects charges of the same polarity on the two plates. The applied voltage creates an electric field within the dielectric and creates an attraction between the opposite charger carriers, thus creating a capacitance between the two terminals. As the voltage applied increase, the charges forced will increase as well, leading to an increase in capacitance. This is why film capacitors have characteristic known as “negative capacitance” or “reverse capacitance”.

MKP383322140JI02W0 also comes with an insulation sleeve that protects it from environmental stresses as it increases the voltage breakdown. The insulation sleeve is also designed to prevent the accumulation of charges within the dielectric film that could lead to insulation leakage.

Conclusion

In conclusion, MKP383322140JI02W0 is a great choice for general purpose applications. Its excellent frequency characteristics, high temperature, and voltage rating make it well-suited for high-power applications such as motor drives, air conditioners, and power factor correction. It also works on the same working principle as other film capacitors. The dielectric material used in MKP383322140JI02W0, polypropylene film, gives the capacitor the advantages of excellent self-healing properties, excellent temperature characteristics, free of maintenance, and high surge current intensity.
