Abstract
An inductor includes a ferromagnetic core, an inductor coil, and a holder. The inductor coil is coiled to form one or more loops around a center. The inductor coil defines a through hole surrounded by an innermost loop to fit about the ferromagnetic core. The holder is configured for holding the ferromagnetic core with the inductor coil. Two ends of the inductor coil protrude out of the holder.
Claims5
An inductor comprising:
- a columniform-shaped ferromagnetic core;
- a long flat inductor coil comprising a plurality of concentric overlapping loops, wherein the plurality of overlapping loops are arranged in a plane, the inductor coil defines a through hole surrounded by an innermost loop of the plurality of overlapping loops;
- the innermost loop to fit around the ferromagnetic core, a first end of the inductor coil protrudes out along a tangent direction of an outermost loop of the plurality of overlapping loops, a second end of the inductor coil protrudes out from the innermost loop of the plurality of overlapping loops and is perpendicular to the first end of the inductor coil;
- and
- a rectangular-shaped holder for holding the ferromagnetic core with the inductor coil, wherein the first and second ends of the inductor coil protrude out of the holder along an opening direction of the holder.
