摘要 |
PROBLEM TO BE SOLVED: To provide a powder compact core including powder of crystalline magnetic material and powder of amorphous magnetic material, and having a superior magnetic property even in a high-frequency band of 1 MHz or higher.SOLUTION: Powder compact core comprises: powder of crystalline material magnetic material; and powder of amorphous magnetic material. When the dependence of an iron loss Pcv (unit: kW/m) measured under the condition that effective maximum magnetic flux density Bis 15 mT on a frequency f(unit: kHz) is represented by the formula (1) below by use of two constants kand k, one constant kis equal to or less than 1.5×10kW/m/kHz/(mT), and the other constant kis equal to or less than 3.0×10kW/m/(kHz)/(mT): Pcv=k×f×B+k×f×B(1). |
