Driven by further electrification in the electric vehicle (EV) market, higher voltage requirements are accelerating in automotive powertrains and safety-related equipment. The components that make up these systems must operate reliably under high-voltage loads. In addition, household charging units for EV batteries are increasingly employing three-phase AC power sources, which likewise demand high-voltage capability.

To meet this market demand, the newly introduced models have undergone a design review to allow operation at higher voltages. While the existing KCA series had a safety-certified voltage of 250Vac (r.m.s.), the new models support 500Vac (r.m.s.) and have acquired safety standard certification for class Y2/X1. Thanks to the revised design, certain capacitance values achieve a lower profile compared to previous products, enabling installation in more space-constrained environments. Furthermore, these additions are offered at a reduced cost versus existing alternatives, supporting long-term cost reduction objectives.
