Abstract
Disclosed herein is a coil component that includes a winding core part and first and second wires wound around the winding core part. The first and second wires constitute at least three winding layers on the winding core part. The same turns of the first and second wires are positioned in mutually different winding layers over a plurality of turns.
Claims20
A coil component comprising:
- a winding core part;
- and
- first and second wires wound around the winding core part, wherein the first and second wires constitute at least three winding layers on the winding core part, and
- wherein same turns of the first and second wires are positioned in mutually different winding layers over a plurality of turns,
- wherein the at least three winding layers include a lower layer closest to the winding core part, an upper layer farther away from the winding core part than the lower layer, and at least one intermediate layer positioned between the lower and upper layers,
- wherein the lower layer includes the first wire,
- wherein the upper layer includes the second wire,
- wherein the intermediate layer includes the first and second wires in a mixed manner,
- wherein an i-th turn (i is an integer equal to or larger than 5) and an (i-th+1) turn of the first wire are wound in the lower layer,
- wherein an (i-th+2) turn of the first wire and an (i-th+1) turn of the second wire are wound in the intermediate layer, and
- wherein an i-th turn and a (i-th+2) turn of the second wire are wound in the upper layer.
