Product Description
This capacitor is widely used in the submitted of electrical power electronics and has the function of isolating the direct current, filtering out the substantial-buy harmonics on the bus aspect, absorbing and guarding IGBT spikes, damping, clamping and the like.Static frequency converter for modern day variable pace transmisson, in which the switching function of semiconductor generates many parasitic singal, as a result,capactiors are required to filter, get rid of ripples and harmonics in the circuit. The self-healing metallized film capacitor can be utilized as a immediate current link and harmonic filtering of an intermediate circuit, and can also be used as an embedding and absorbing capacitor in a contorl circuit.The uncooked material of the capacitor has gone through a specific metallzation coating -zHangCZPTan sq. resistance. By carrying out a unique vacuum evaporation process on oneside of the polypropylene foundation movie, the thickness of the coating layer is various positions of the film.The capacity of capacitor to take care of large recent can be significantly enhanced by increasing the plant degere at the link lead.

1.Utilized to take up or filter substantial-frequency impulse in high-electrical power large-frequency swich
two.Low ESR, high ripple current and large current shock handling capabilities 
3. Low Ls, good high frequency characteristics
four.Self-healing property
5.Long lifetime
 6.CZPT case, Filled with resin
