发明名称 MAGNETIC CORE AND INDUCTANCE COMPONENT USING THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a low cost magnetic core having excellent core loss characteristics and DC superimposition characteristics and to provide an inductance component using the same. <P>SOLUTION: The magnetic core includes at least one or more gaps of magnetic paths. A bonded magnet made of a rare earth element magnet powder having an intrinsic coercive force of 20×79 kAT/m (20 kOe) or more, a Curie temperature Tc of 300°C or higher and a powder mean particle size of 2.5 to 50μm, is inserted into the gap of the magnetic core. The bonded magnet made of an SmCo magnet powder containing a composition of Sm(Fe<SB>0.15-0.25</SB>Cu<SB>0.06-0.08</SB>Zr<SB>0.02-0.03</SB>Co<SB>Bal</SB>)<SB>7.0-8.5</SB>and having a powder mean particle size of 2.5 to 50μm and a resin is inserted into the gap. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p>
