Reduce the excessive voltage from the turning on and off of power semiconductors and lower the dv/dt value.

OKAYA high pulse capacitors are made up on non-inductive metallized polypropylene film. This provides excellent anti-pulse characteristics and low insertion loss which are generally regarded as important features necessary for the capacitor.

Our line of metallized polypropylene capacitors feature high insulation resistance and low dissipation. This permits low insertion loss from low frequency to high frequency in addition to low heating and better endurance to surges. In your application, this means excellent electrical characteristics required for high frequency circuits and high voltage circuits.
