DUST CORE, METHOD OF PRODUCING THE DUST CORE, ELECTRICAL/ELECTRONIC COMPONENT INCLUDING THE DUST CORE, AND ELECTRICAL/ELECTRONIC EQUIPMENT INCLUDING THE ELECTRICAL/ELECTRONIC COMPONENT MOUNTED THEREON

Document Type and Number:

Japanese Patent JP2018170304

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a dust core containing powder of a crystalline magnetic material such as carbonyl iron, which has excellent magnetic characteristics.SOLUTION: A dust core 1 contains powder of a crystalline magnetic material and powder of amorphous magnetic material. The dust core is characterized in that a first mixture ratio is 75 mass% or more and 95 mass% or less, the first mixture ratio being a mass ratio of the content of powder of the crystalline magnetic material with respect to the sum total of the content of powder of the crystalline magnetic material and the content of powder of the amorphous magnetic material.SELECTED DRAWING: Figure 1
