Product Description
This capacitor is widely utilized in the filed of electricity electronics and has the perform of isolating the direct recent, filtering out the high-get harmonics on the bus aspect, absorbing and safeguarding IGBT spikes, damping, clamping and the like.Static frequency converter for modern variable pace transmisson, in which the switching perform of semiconductor generates several parasitic singal, for that reason,capactiors are necessary to filter, eradicate ripples and harmonics in the circuit. The self-healing metallized film capacitor can be utilised as a direct current link and harmonic filtering of an intermediate circuit, and can also be employed as an embedding and absorbing capacitor in a contorl circuit.The uncooked content of the capacitor has been through a specific metallzation coating -zHangCZPTan square resistance. By carrying out a particular vacuum evaporation approach on oneside of the polypropylene foundation movie, the thickness of the coating layer is diverse positions of the movie.The potential of capacitor to take care of large present can be greatly enhanced by escalating the plant degere at the link guide.

one.Utilized to take in or filter higher-frequency impulse in higher-energy large-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
five.Long lifetime
 6.CZPT case, Filled with resin
