MKU series is a new alloy powder series through Mirrack's own innovation. It's prominently characterized itself with superior low loss, while maintaining a very good DC bias performance. What's more, it's much more cost-effective than Fe-Si powder (compatible to Magnetics XFlus, CSC Mega Flus, Arnold Fluxsan) and Super Sendust powder (compatible to Magnetics Kool Mu Max, Arnold SH series).

It's widely applied to flyback transformer, resonant inductor, power factor correction choke / boost (PFC choke / PFC boost) for UPS, inverter air conditioner, industrial power supply, solar / PV inverter as well as electric vehicle, etc.

● Excellence in cost-effectiveness
