Abstract
In the wound inductor component, a flange is connected to a first end of a winding core in the central axial line direction, and protrudes from both sides of the winding core along a height direction. A cover member covers a portion from the upper end of the 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, an area of a first region at an upwardly protruding portion of the flange defined by a boundary between the flange and the winding core, a straight line parallel to the central axial line and passing through the upper end of the flange, and a region surrounded by a portion of the surface of the flange is larger than an area of a similarly defined second region at a downwardly protruding portion of the flange.
Claims20
A wound inductor component comprising:
- a columnar winding core;
- a first flange and a second flange respectively connected to both ends of the winding core in a central axial line direction of the winding core, the first and second flanges each protruding from both of opposite sides of the winding core along a first line direction that is orthogonal to the central axial line direction of the winding core and orthogonal to a mounting surface at the time of mounting, 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 of the sides of the winding core in the first line direction, a portion from a farthest end of one side of the first flange in the first line direction to a farthest end on one side of the winding core in the first line direction,
- wherein
- when viewed in a cross section including the central axial line and along the first line direction,
- when a first region is defined as a region surrounded by a first straight line extending in the first line direction and passing through a boundary between the first flange and the winding core, a second straight line parallel to the central axial line and passing through the farthest end of one side of the first flange in the first line direction, and a first portion of an inner surface of the first flange, and
- a second region is defined as a region surrounded by a third straight line extending in the first line direction and passing through the boundary between the first flange and the winding core, a fourth straight line parallel to the central axial line and passing through a farthest end of an other side of the first flange, opposite to the one side of the first flange, in the first line direction, and a second portion of the inner surface of the first flange,
- an area of the first region is larger than an area of the second region.
