Product Description
This capacitor is widely used in the filed of power electronics and has the function of isolating the direct current, filtering out the high-order harmonics on the bus side, absorbing and protecting IGBT spikes, damping, clamping and the like.Static frequency converter for modern variable speed transmisson, in which the switching function of semiconductor generates many parasitic singal, therefore,capactiors are needed to filter, eliminate ripples and harmonics in the circuit. The self-healing metallized film capacitor can be used as a direct current connection and harmonic filtering of an intermediate circuit, and can also be used as an embedding and absorbing capacitor in a contorl circuit.The raw material of the capacitor has undergone a special metallzation coating -zhebian square resistance. By carrying out a special vacuum evaporation process on oneside of the polypropylene base film, the thickness of the coating layer is different positions of the film.The ability of capacitor to handle large current can be greatly improved by increasing the plant degere at the connection lead.

1.Used to absorb or filter high-frequency impulse in high-power high-frequency swich
2.Low ESR, high ripple current and large current shock handling capabilities 
3. Low Ls, good high frequency characteristics
4.Self-healing property
5.Long lifetime
 6.Plastic case, Filled with resin
