  • Publication number: 20240331912
    Abstract: An inductor component includes an element including insulating layers that are laminated, and a coil in the element and helically wound about an axis. The coil includes a first outer coil wiring layer outermost on a first side in a direction of the axis, a second outer coil wiring layer outermost on a second side in the direction of the axis, and at least one inner coil wiring layer between the first and second outer coil wiring layers. The first outer coil wiring layer, the at least one inner coil wiring layer, and the second outer coil wiring layer are laminated while alternating with the insulating layers. The insulating layer between the first outer coil wiring layer and the inner coil wiring layer adjacent to the first outer coil wiring layer in the direction of the axis has a thickness smaller than or equal to 6.5 ?m.

  • Publication number: 20240071681
    Abstract: An inductor component including an element body and an inductor wiring having a lower side portion including a portion closest to a bottom surface of an element body and extending along the bottom surface. In the element body, a range from a first virtual plane to a second virtual plane is defined as a wiring range. A first protrusion portion of a first electrode protrudes from an end of a first bottom surface electrode portion of the first electrode on a second end surface side toward the second end surface side. A maximum dimension of the first protrusion portion in a direction perpendicular to a first main surface is smaller than a maximum dimension of the first bottom surface electrode portion in the direction perpendicular to the first main surface. At least a part of the first protrusion portion on the bottom surface is located within the wiring range.

  • Publication number: 20240062950
    Abstract: An inductor component includes an element body and an inductor wiring in the element body. When viewed in a direction perpendicular to a first main surface, the inductor wiring has a circling path wound one or more turns. The element body includes a main body having an insulating property and a first covering layer having optical properties different from those of the main body. The first covering layer is parallel to the first main surface, and is on the first main surface side with respect to an end of the circling path on the first main surface side. When viewed in a direction perpendicular to the first main surface, the first covering layer overlaps the entire circling path, and a range surrounded by an outer edge of the first covering layer is smaller than a range surrounded by an outer edge of the main body.

  • Publication number: 20220392699
    Abstract: An inductor component comprising a base; a coil in the base body and wound along a direction of an axis; and first and second external electrodes disposed on the base body and electrically connected to the coil. The base body includes first and second end surfaces and a second end surface at ends in the length direction, first and second side surfaces at ends in the width direction, and bottom and top surfaces at ends in the height direction. The first and second external electrodes are respectively disposed toward the first and second end surfaces with respect to a center in the length direction and exposed from an outer surface of the base body. When viewed from the first end surface in the length direction, at least a part of a respective portion of the first and second external electrodes exposed from the outer surface do not overlap.

  • Patent number: 9165706
    Abstract: A coil component is provided with a first magnetic substrate, a laminate body, and a second magnetic substrate. A coil is formed inside the laminate body. In the coil, a plurality of coil patterns provided on one surface of an insulation layer and a plurality of coil patterns provided on the other surface of the insulation layer are connected at multiple locations through vias. The coil patterns are configured in such a manner that a portion which is in contact with each via has a wider width widened with equal size from the center of a coil pattern to both sides thereof in the width direction, and a portion which is adjacent to the portion having the wider width across a gap has a narrower width(s) narrowed with equal size from the center of the coil pattern to both sides thereof in the width direction.
