Abstract
A multilayer inductor device includes a planar substrate, a ferrite body, and an outer and an inner conductive coil. The substrate includes plural dielectric layers with the ferrite body is disposed in the substrate. The outer and inner conductive coils are helically wrapped around the ferrite body. The outer conductive coil includes first upper conductors, first lower conductors, and first conductive vias vertically extending through the substrate and conductively coupled with the first upper and lower conductors. The inner conductive coil includes second upper conductors, second lower conductors, and second conductive vias vertically extending through the substrate and conductively coupled with the second upper and lower conductors. The inner conductive coil is disposed between the outer conductive coil and the ferrite body.
