Selection Guide
When selecting capacitors from the KY series, consider these key parameters:
The KY series excels in applications with high ripple current demands. For applications with lower ripple current requirements, consider the KZE series for cost optimization.
While the KY series has enhanced thermal performance, proper thermal design remains critical in high-power applications. Consider PCB copper area, thermal vias, and system cooling in your design.
Use NCC's life prediction models to determine actual operational life under your specific conditions. The 8,000-10,000 hour rating is at rated temperature and voltage.
FAE Note: The KY series is optimal for industrial applications with high ripple current requirements. For consumer applications with modest ripple demands, the KZE series offers better cost-effectiveness.
