MKP385420063JC02R0 Application Field and Working Principle

Film capacitors are divided into two categories of metallized film capacitors and plastic film capacitors. MKP385420063JC02R0 belongs to metallized film capacitors. Metallized film capacitors use polyester and polypropylene film substrates, and a metal layer is vapor-deposited on one or both sides of the dielectric medium to form a stable electrical network. Through this process, a high-density electric field will be generated in the metal layer, which will form an effective barrier to external electromagnetic interference.

The capacity of metallized film capacitors is large and the insulation resistance is good. The characteristic of no thermal aging is excellent, and it has good stability and low noise. MKP385420063JC02R0 is an aluminum polymer chip capacitor. There is a typical micro-distortion structure between the two electrodes, which ensures high capacitance, small size and low ESR value. The product has high temperature resistance, complete specifications, large capacity, and stable performance.

The main application field of MKP385420063JC02R0 contains equipments with high precision control requirements, such as electrical automation control, power switching converter circuits, inverter circuitry, electro-plating control, medical device, digital switching power supply, DC to DC converter, and more. MKP385420063JC02R0 ideal for bypass, blocking, coupling, and decoupling applications.

The MKP385420063JC02R0 working principle is similar to that of a normal capacitor. Using the electric field in the metal layer to store energy, the electric energy source constantly vibrates between the two electrodes and creates current. The dielectric medium provides insulation between the electrodes, and when the polarity of the voltage changes, the polarization of the dielectric medium is subject to the same polarity reversal, which causes the current to flow in the opposite direction and forms a circular current.

The linear size, structure and material of MKP385420063JC02R0 have a great influence on its capacitance. In the same size, the larger the capacity, the higher the permittivity of the dielectric medium, the smaller its own volume and the less the series inductance, the higher its ESR value. Compared with other capacitors, the temperature coefficient of MKP385420063JC02R0 is smaller.

In conclusion, MKP385420063JC02R0 of metallized film capacitor is characterized by its large capacity, good insulation resistance, no thermal aging, high temperature resistance, good stability, low noise, and low ESR. It has a wide range of applications, most suitable for precision electric control equipment and can improve the quality of the device\'s work. In addition, the linear size of the structure and the material of MKP385420063JC02R0 will affect its performance indexes, so it is necessary to pay more attention to the selection.
