Ferrite ceramic composition, ceramic electronic component, and method for manufacturing ceramic electronic component
A ceramic electronic component includes a magnetic section composed of a ferrite material and a coil conductor containing Cu as its main constituent. The magnetic section is formed from Ni—Cu—Zn ferrite which falls within the range specified by (x, y)=A (25, 1), B (47, 1), C (47, 7.5), D (46, 7.5), E (46, 10), F (30, 10), G (30, 7.5), and H (25, 7.5) when the molar content x of Fe2O3 and the molar content y of Mn2O3 are represented by (x, y). A CuO molar content of 0.5 to 10.0 mol %, a ZnO content of 1.0 to 35.0 mol %, a MgO content of 5.0 to 35.0 mol %, and NiO as the balance is present. Even when co-firing with a conductive material containing Cu as its main constituent, insulation properties are ensured, favorable electrical properties are achieved, and a ceramic electronic component is achieved.
