PROBLEM TO BE SOLVED: To provide a ferrite composition having high resistivity, and providing characteristics of high initial magnetic permeability and saturated magnetic flux density and low power loss (MHz band) in good balance; a ferrite core composed of the ferrite composition; and electronic parts having the ferrite core.SOLUTION: This ferrite composition includes a main component composed of 44.0-49.95 mol% FeO, 1.0-20.0 mol% CuO, 13.0-19.9 mol% ZnO, 0.01-5.4 mol% MnOand the rest of nickel oxide, and an accessory component composed of 2-65 ppm P and 40-5,000 ppm ZrO, further containing ≤10 ppm Pb and ≤10 ppm Cd, each to 100 pts.wt. main component. The total content of FeOand MnOis 50.1 mol% or less. |
