Title:
LAMINATED COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2016/072428
Kind Code:
A1
Abstract:
The present invention provides a laminated coil component having a magnetic section containing Fe, Zn, V and Ni and optionally containing Mn and/or Cu, and also having a coil-shaped conductor section containing copper, the laminated coil component being characterized in that relative to the sum of the Fe content converted to Fe2O3, the Zn content converted to ZnO, the V content converted to V2O5, the Ni content converted to NiO, and if present, the Cu content converted to CuO and the Mn content converted to Mn2O3, the magnetic section contains Fe in the amount of 34.0-48.5 mol% when converted to Fe2O3, Zn in the amount of 6.0-45.0 mol% when converted to ZnO, Mn in the amount of 0-7.5 mol% when converted to Mn2O3, Cu in the amount of 0-5.0 mol% when converted to CuO, and V in the amount of 0.5-5.0 mol% when converted to V2O5. Furthermore, this laminated coil component is capable of using the copper as an internal conductor, and exhibits low variation in specific resistance even when mass-produced on an industrial scale.
