MAGNETIC CORE AND MAGNETIC COMPONENT

Provided is a magnetic core in which metal magnetic particles occupy an area of 75% to 90% on a cross-section. The metal magnetic particles include first large particles having a crystalline metal material and having a Heywood diameter of 3 μm or more on the cross-section of the magnetic core, and s...

More Information
Summary:Provided is a magnetic core in which metal magnetic particles occupy an area of 75% to 90% on a cross-section. The metal magnetic particles include first large particles having a crystalline metal material and having a Heywood diameter of 3 μm or more on the cross-section of the magnetic core, and second large particles having a nanocrystal structure or an amorphous structure and having a Heywood diameter of 3 μm or more, and an insulation coating of the first large particles is thicker than an insulation coating of the second large particles.
