摘要: A multilayer inductor component has a multilayer part having a plurality of magnetic layers laminated therein and a conductor part arranged within the multilayer part. The magnetic layers are formed from a ferrite material and an additive. The ferrite material contains Fe2O3, NiO, CuO, and ZnO. Fe2O3 is 30 to 45 mol %. NiO is 45 to 58 mol %. CuO is 6 to 10 mol %. ZnO is 0 to 3 mol %. The additive contains CoO. The content of CoO is 0.1 to 2.5 mass % with respect to the ferrite material as a whole. The multilayer inductor component has an impedance peak of 500Ω or greater at an operating frequency of 1 GHz or higher.

摘要: The ferrite paste according to the present invention contains a ferrite powder and an organic vehicle, and the organic vehicle contains an organic solvent and a binder made of a polyvinyl acetal resin and ethyl cellulose. The binder content in the ferrite paste is at least 3.0 weight parts and no more than 5.0 weight parts per 100 weight parts of the ferrite powder, and the polyvinyl acetal resin content is at least 0.5 weight part and no more than 2.0 weight parts per 100 of the weight parts ferrite powder. The ethyl cellulose content is the remainder of subtracting the polyvinyl acetal resin content from the binder content.
