Abstract
A coil component includes a core including a winding core portion, a first flange portion, and a second flange portion, and a first wire and a second wire that are wound around the winding core portion in the same direction and that form a winding portion. The winding portion includes a second intersecting portion along a third side surface of the winding core portion at a position on the winding portion nearest to the second flange portion.
Claims4
A coil component comprising:
- a core including a winding core portion that extends in a length direction of the coil component, a first flange portion that is disposed on a first end portion of the winding core portion in the length direction, and a second flange portion that is disposed on a second end portion of the winding core portion in the length direction;
- a first wire and a second wire that are wound around the winding core portion in the same direction and that form a winding portion, the winding portion including an intersecting portion along a side surface of the winding core portion at a position on the winding portion nearest to the first flange portion or the second flange portion;
- a first terminal electrode that is disposed on a bottom part of the first flange portion in a height direction of the coil component perpendicular to the length direction and that is connected to a first end portion of the first wire;
- a second terminal electrode that is disposed on the bottom part of the first flange portion and that is connected to a first end portion of the second wire;
- a third terminal electrode that is disposed on a bottom part of the second flange portion in the height direction and that is connected to a second end portion of the first wire;
- and
- a fourth terminal electrode that is disposed on the bottom part of the second flange portion and that is connected to a second end portion of the second wire,
- the first flange portion includes a first leg portion and a second leg portion that protrude from a bottom surface in the height direction,
- the first leg portion and the second leg portion are spaced from each other in a width direction, and
- the first end portion of the first wire is connected to the first terminal electrode at a location other than the first leg portion such that the first end portion of the first wire is connected to the first terminal electrode at a location between the first leg portion and a first side surface of the first flange portion, and the first end portion of the second wire is connected to the second terminal electrode at a location other than the second leg portion such that the first end portion of the second wire is connected to the second terminal electrode at a location between the second leg portion and a second side surface of the first flange portion opposite to the first side surface.
