<P>PROBLEM TO BE SOLVED: To provide a Mn-Zn ferrite which is low in deterioration of direct current superimposing characteristic and has both of a high saturation flux density and a low loss at high temperatures compatively. <P>SOLUTION: The Mn-Zn ferrite contains 53.5-55.2 mol % Fe<SB>2</SB>O<SB>3</SB>, 2.5-6.5 mol % ZnO and the remainder being MnO as a fundamental composition, and 0.002-0.005 wt % SiO<SB>2</SB>, 0.01-0.05 wt % CaO, 0.02-0.08 wt % V<SB>2</SB>O<SB>5</SB>, and 0.01-0.05 wt % Nb<SB>2</SB>O<SB>5</SB>as a sub-components. <P>COPYRIGHT: (C)2004,JPO |
