PROBLEM TO BE SOLVED: To provide a ferrite composition having high resistivity, and providing both high initial magnetic permeability and saturated magnetic flux density and low power loss (MHz band) in good balance, and to provide 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 47.0-49.95 mol% FeO, 1.0-12.0 mol% CuO, 28.0-32.5 mol% ZnO, 0.01-2.4 mol% MnOand the rest of nickel oxide, and an accessory component composed of 2-65 ppm P and 40-4,500 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. |
