POWDER CORE, POWDER CORE MANUFACTURING METHOD, AND METHOD FOR ESTIMATING EDDY CURRENT LOSS IN POWDER CORE

An eddy current loss at a frequency of 3,000 Hz is set to less than 150 W/kg by setting a single particle diameter-equivalent diameter d s of soft magnetic metal powder represented by the following formula to 210 µm or less. In the formula, d s represents a single particle diameter-equivalent diamet...
