发明名称 MAGNETIC CORE AND INDUCTANCE COMPONENT USING IT
摘要 <P>PROBLEM TO BE SOLVED: To provide an inexpensive magnetic core having superior coreloss characteristics and DC superimposing characteristics, and to provide an inductance component using the magnetic core. <P>SOLUTION: The inductance component is constituted of the magnetic core 11 having gaps into which bonded magnets are inserted at least one or more places of its magnetic path and a winding 4 wound around the magnetic core 11 by at least one turn or more. Each bonded magnet has an intrinsic coercive force of &ge;10 kOe, a Tc of &ge;500&deg;C, and a specific resistance of &ge;1.0 &Omega;cm, is composed of rare-earth magnet powder having a mean particle diameter of 2.5-50 &mu;m and a resin, and is suppressed in the increase of the hysteresis loss of its core to &le;20% as compared with that before insertion. <P>COPYRIGHT: (C)2005,JPO&NCIPI
