Abstract
In a wound inductor component, a first flange and a second flange are connected to both ends of a winding core in the central axial line direction, and protrude from the winding core to both sides in a height direction. A cover member covers a portion from the upper end of the first flange to the upper end of the winding core from above. In a sectional view including the central axial line and along the height direction, a first average distance, which is an average distance in the height direction from the upper end of the first flange to the upper end of the cover member, is 25% or more and 45% or less (i.e., 25% to 45%) of a second average distance, which is an average distance in the height direction from the upper end of the winding core to the upper end of the cover member.
Claims20
A wound inductor component comprising:
- a columnar winding core;
- a first flange and a second flange which are connected to both ends of the winding core in a central axial line direction of the winding core and protrude from the winding core to both sides in a first direction orthogonal to the central axial line direction of the winding core, when a central axial line is defined as a line through which a center of the winding core passes in an extending direction of the winding core, and the central axial line direction is defined as a direction in which the central axial line extends;
- a wire wound around the winding core;
- and
- a cover member covering, from one side in the first direction, a portion from an end of the first flange on one side in the first direction to an end of the winding core on one side in the first direction,
- wherein when viewed in a sectional view including the central axial line and along the first direction, a first average distance that is an average distance in the first direction from an end of the first flange on one side in the first direction to a surface of the cover member on one side in the first direction is from 25% to 45% of a second average distance that is an average distance in the first direction from an end of the winding core on one side in the first direction to the surface of the cover member on one side in the first direction.
