<P>PROBLEM TO BE SOLVED: To provide a Mn-Zn ferrite which exhibits a low deterioration of direct current superimposing characteristic, and exhibits both of a high saturation flux density and a low loss at high temperature in combination. <P>SOLUTION: The Mn-Zn ferrite is composed of 54.0-56.0 mol% Fe<SB>2</SB>O<SB>3</SB>, 6.0-8.0 mol% ZnO and the remainder being MnO as a fundamental composition, and 0.002-0.01 wt.% SiO<SB>2</SB>, 0.01-0.1 wt.% CaO, 0.01-0.1 wt.% V<SB>2</SB>O<SB>5</SB>, 0.01-0.1 wt.% Nb<SB>2</SB>O<SB>5</SB>, 0.1-1.1 wt.% NiO and 0.05-0.2 wt.% Sb<SB>2</SB>O<SB>3</SB>are simultaneously incorporated as sub-components. <P>COPYRIGHT: (C)2008,JPO&INPIT |
