Title:
POWDER MAGNETIC CORE AND MAGNETIC ELEMENT USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/103709
Kind Code:
A1
Abstract:
Provided is a magnetic element compatible with high current, wherein the frequency thereof can be increased; the size thereof can be reduced; and the withstand voltage thereof can be improved. A powder magnetic core is comprised of metal magnetic powders, an inorganic insulation material, and a thermosetting resin. The metal magnetic powders have a Vickers hardness (Hv) of 230 ≤ Hv ≤ 1,000. The inorganic insulation material has a compressive strength of not more than 10,000 kg/cm2, and is mechanically disintegrated. The mechanically-disintegrated inorganic insulation material and the thermosetting resin are provided between the metal magnetic powders.
