Product Description
This capacitor is commonly used in the filed of power electronics and has the function of isolating the direct current, filtering out the substantial-get harmonics on the bus side, absorbing and safeguarding IGBT spikes, damping, clamping and the like.Static frequency converter for modern variable speed transmisson, in which the switching perform of semiconductor generates several parasitic singal, therefore,capactiors are required to filter, get rid of ripples and harmonics in the circuit. The self-therapeutic metallized film capacitor can be used as a direct present link and harmonic filtering of an intermediate circuit, and can also be utilised as an embedding and absorbing capacitor in a contorl circuit.The uncooked content of the capacitor has undergone a specific metallzation coating -zHangCZPTan sq. resistance. By carrying out a unique vacuum evaporation process on oneside of the polypropylene base film, the thickness of the coating layer is diverse positions of the film.The capability of capacitor to take care of large recent can be drastically enhanced by increasing the plant degere at the link guide.

Functions:
1.Utilised to soak up or filter high-frequency impulse in large-power high-frequency swich
two.Low ESR, high ripple current and large current shock handling capabilities 
three. Low Ls, good high frequency characteristics
four.Self-healing property
five.Long lifetime
 6.CZPT case, Filled with resin
