Soft Magnetic Powder, Dust Core, Magnetic Element, And Electronic Device

Abstract

A soft magnetic powder contains: Fe as a main component; Si having a content of 2.5 mass % or more and 7.5 mass % or less; Cr having a content of 0.5 mass % or more and 10.0 mass % or less; Al having a content of 0.05 mass % or more and 0.50 mass % or less; C having a content of 0.005 mass % or more and 0.050 mass % or less; and an impurity. When 0.5 g of the soft magnetic powder weighed is used as a test object, the test object is placed in a cylinder having an inner diameter of 8 mm and an axis in an up-down direction, and a withstand voltage is measured in a state in which a load of 20 kgf (196 N) is applied to the test object by sandwiching the test object between electrodes from above and below, the withstand voltage is 400 V or more.
