and a small temperature coefficient of coercivity.
■特 長
Features
NMF®-12 Series
量産フェライト磁石として
世界最高レベルの磁気特性を実現
保磁力(H cJ)の温度係数が小さく、
低温域での減磁耐力に優れる
The highest magnetic characteristics available in a mass-produced
ferrite magnet
Small temperature coefficient of coercivity (HcJ) leads to
high demagnetization resistance at low temperatures
