- Product
- Magnetic Powder Coresare distributed air gap cores made from ferrous alloy powders for low losses at high frequencies. Small air gaps distributed evenly throughout the cores increase the amount of DC that can be passed through the winding before core saturation occurs.
MPC products include MPP, High-Flux, Sendust and Super Flux which are composed of different metal alloy.
Through their functional properties of automatics voltage control, power conversion and electromagnetic wave and noise reduction, these MPC products are the core parts in all kinds of power supply for electronic and telecomunication appliances.
