鐵鎳鉬（MPP）磁粉芯---鐵鎳鉬（MPP）磁粉芯的Q值最高，而且磁芯損耗最低。MPP鐵鎳鉬磁粉芯的溫度性能和交流（AC）磁通性能最穩定。它具有最寬的磁導率可選範圍，是開關電源中直流（DC）輸出濾波電感器的最佳選用材料，在兆赫茲級的應用場合是非常適用的,MPP鐵鎳鉬磁粉芯最適合用於精密音頻調諧電路，高Q值濾波器，負載線圈，射頻（RFI）濾波器和許多其它精密電感器的應用場合，如軍工產品，醫療設備等。

MPP (Molypermalloy Powder)

Distributed air gap toroid cores made from nickel, iron and molybdenum alloy powder. 80% nickel, 2% molybdenum iron alloy particles are compacted into toroidal shapes. Material permeability's range from 60µi to 173µi with standard core sizes from 6.35 to 58.0mm. Larger core sizes are available from our Genalex™ range of toroid cores. Cores are coated with an epoxy coating which provides a tough outer surface with a minimum breakdown voltage of 500Vac. MPP cores are colour coded in dark blue.
