软磁性部件、电抗器、磁粉芯用粉末和制造磁粉芯的方法
Abstract:
本发明涉及软磁性部件、电抗器、磁粉芯用粉末和制造磁粉芯的方法。一种软磁性部件被形成为使得：当在100A/m的施加磁场中微分相对磁导率由第一微分相对磁导率μ’L表示时，并且当在40kA/m的施加磁场中微分相对磁导率由第二微分相对磁导率μ’H表示时，所述第一微分相对磁导率μ’L与所述第二微分相对磁导率μ’H的比率满足μ’L/μ’H≤10的关系，并且在60kA/m的施加磁场中磁通密度为1.15T以上。
Abstract(English):

A soft magnetic member is formed such that, when a differential relative permeability in an applied magnetic field of 100 A/m is represented by a first differential relative permeability µ'L, and when a differential relative permeability in an applied magnetic field of 40 kA/m is represented by a second differential relative permeability µ'H, a ratio of the first differential relative permeability µ'L to the second differential relative permeability µ'H satisfies a relationship of µ'L/µ'H‰¤10, and a magnetic flux density in an applied magnetic field of 60 kA/m is 1.15 T or higher.
