Kool Mµ® Hƒ Cores

Kool Mµ® Hƒ powder cores are made from distributed gap alloy powder optimized for frequencies 200-500 kHz. Exhibiting approximately 35% lower losses when compared to Kool Mµ, Kool Mµ Hƒ is a cost-effective solution for minimizing power losses in high frequency power supplies using GaN or SiC, high efficiency power supplies, and Uninterruptible Power Supplies (UPS).
