Abstract: A planar inductor device includes a ferrite body and a conductive pathway, The ferrite body extends around an opening in the ferrite body. The conductive pathway includes an input section, a current-splitting section, a coil section, a current-combining section, and an output section connected with each other, the input section extending toward the opening in the ferrite body. The current-splitting section includes a plurality of conductive coils joined with the conductive pathway and electrically disposed parallel to each other. The coil section includes the conductive coils helically wrapped around the ferrite body. The current-combining section includes the conductive coils joined with each other. The output section includes the joined conductive coils extending out of the ferrite body.
