 2 Product Features

This capacitor uses roughened polypropylene film as the medium, specific aluminum foil as the electrode, and wound by non-inductive winding.

High vacuum drying and impregnation technology is used to remove all residual moisture and air in the capacitor, and the impregnating agent filled has good insulation performance and low temperature resistance.

It can withstand the impact of instantaneous large current and high voltage, with no capacity attenuation, good heat dissipation performance, and good low temperature resistance.
