Film Capacitors: MKP385247200JFM2B0 Application Field and Working Principle

Introduction

Film capacitors, also called plastic film capacitors, are widely used in a variety of applications, for example, power electronics, medical equipment, automotive, and aerospace. Among a variety of film capacitors, MKP385247200JFM2B0 is one of the most popular ones. It has a high energy density, high-ripple power and ultra-steady DC bias level. In this article, its application field and working principle will be discussed in detail.

Application Field of MKP385247200JFM2B0

Based on its high energy density, ultra-steady DC bias level and high-ripple power, MKP385247200JFM2B0 can generally be used in:

• Lighting and ballast application, such as in LED lighting, street lights, and residential lights.
• Power conversion, including switching power supplies, DC-DC converters, UPS, and modern energy-saving electrothermal products.
• High-end drive application, including high-speed hard disk motors, servo drives, brushless DC motors, etc.

Working Principle of MKP385247200JFM2B0

MKP385247200JFM2B0 mainly consists of an anode terminal, a cathode terminal, an insulating film, and meet the insulation strength of the medium. Its main working principle is as follows:

• When the terminals in the capacitor are connected to the direct current, a uniform electric field is formed in the insulation film, which charges the capacitor.
• When the terminals is connected to alternating current, the electric field formed in the insulation film will alternate, and the charge will also alternate.
• When charging, electrons will move from the anode terminal to the cathode terminal, and when discharging, electrons will move from the cathode terminal to the anode terminal.
• During operation, positive and negative polarization charge will be generated on the surface of the insulation film, forming a dielectric that will oppose the current flow.
• When reverse bias is applied to the terminals, charge will distribute in the opposite direction, thus reducing the capacitance significantly.

Conclusion

To sum up, MKP385247200JFM2B0 is a popular film capacitor and is widely used in various fields, such as lighting and ballast application, power conversion, and high-end drive application. Its working principle is mainly about the formation of an electric field in the insulation film, which then charges the capacitor, and the charge will also alternate when it is connected to alternating current. Meanwhile, a dielectric is formed on the surface of the insulation film, which will oppose the current flow.
