Abstract
A coil component includes a body including a plurality of effective layers stacked in one direction; a coil portion embedded in the body, the coil portion including a plurality of coil patterns respectively disposed in the plurality of effective layers, the coil portion further including a lead-out pattern; and a core penetrating through an interior of the coil portion, wherein the coil portion further includes a resistance reducing portion extending from an outer circumferential surface of each of the coil patterns to an outside of the core in a respective one of the effective layers in a radially outward direction of the coil portion.
Claims19
A coil component comprising:
- a body including a plurality of effective layers stacked in one direction;
- a coil portion embedded in the body, the coil portion including a plurality of coil patterns respectively disposed in the plurality of effective layers, the coil portion further including a lead-out pattern;
- and
- a core penetrating through an interior of the coil portion,
- wherein the coil portion further includes a resistance reducing portion extending from an outer circumferential surface of each of the coil patterns to an outside of the core in a respective one of the effective layers in a radially outward direction of the coil portion, and
- wherein the resistance reducing portion is arranged between a vertex of each of the effective layers and a respective one of the coil patterns.
A coil component comprising:
- a coil portion including a plurality of coil patterns connected to each other;
- and
- a body including a core formed by stacking a plurality of effective layers in which the coil patterns are respectively disposed, the core penetrating through an interior of each of the coil patterns,
- wherein each of the coil patterns includes at least one resistance reducing portion extending to an outside of each of the coil patterns, opposing the interior of each of the coil patterns, to increase a cross-sectional area of each of the coil patterns,
- wherein a cross-sectional area of the at least one resistance reducing portion increases and then decreases in a circumferential direction of the core.
A coil component comprising:
- a body including a plurality of effective layers stacked in one direction;
- a coil portion embedded in the body, the coil portion including a plurality of coil patterns respectively disposed in the plurality of effective layers, the coil portion further including first and second lead-out patterns on opposite ends of the coil portion;
- and
- a core penetrating through an interior of each of the coil patterns,
- wherein at least one of the plurality of coil patterns includes a resistance reducing portion and a portion having a via,
- in a radial direction of the coil portion, a width of the resistance reducing portion is larger than a width of the at least one of the coil patterns, and
- the resistance reducing portion of the at least one of the coil patterns is arranged between a vertex of a corresponding one of the effective layers and a center axis of the core.
