Abstract

A coil component includes a first core including a support portion, a core portion protruding from the support portion, and a sidewall portion protruding from the support portion and partially surrounding the core portion, the sidewall portion including first and second sidewalls connected to each other, and surfaces of the first core opposing the first and second sidewalls being open, a winding-type coil disposed on the first core, and a second core attached to the first core.

Claims

1. A coil component, comprising:

a first core including a support portion, a core portion protruding from the support portion, and a sidewall portion protruding from the support portion and partially surrounding the core portion, the sidewall portion including first and second sidewalls connected to each other, and surfaces of the first core opposing the first and second sidewalls being open;

a winding-type coil disposed on the first core; and

a second core attached to the first core.

2. The coil component of claim 1, wherein outer surfaces of the first and second sidewalls are perpendicular to each other.

3. The coil component of claim 1, wherein the coil includes a winding portion, a center of which is coupled to the core portion and first and second lead portions extend from the winding portion in different directions on the support portion.

4. The coil component of claim 3, wherein the first and second lead portions extend from the winding portion in directions perpendicular to each other on the support portion.

5. The coil component of claim 4, wherein the first and second lead portions are folded downwardly of the support portion, respectively.

6. The coil component of claim 5, wherein the first lead portion is folded once downwardly from the support portion in parallel with a direction in which the first lead portion extends in an opposite direction to the direction in which the first lead portion extends, and

the second lead portion is folded once downwardly of the support portion in a direction parallel with a direction in which the second lead portion extends in an opposite direction to the direction in which the second lead portion extends, and is folded once more in perpendicular to a direction in which the second lead portion extends.

7. The coil component of claim 5, wherein the first and second lead portions are parallel with each other below the support portion.

8. The coil component of claim 1, wherein the second core has a flat plate shape.

9. The coil component of claim 8, wherein the second core is attached to the first core with an adhesive.

10. The coil component of claim 1, wherein the first and second cores include magnetic powder particles.

11. A coil component, comprising:

a first core having two open surfaces adjacent each other and two closed surfaces adjacent each other, the respective open surfaces opposing the respective closed surfaces;

a coil disposed on the first core having a winding shape; and

a second core attached to the first core.

12. The coil component of claim 11, wherein the two open surfaces are vertically adjacent each other, and

the two closed surfaces are vertically adjacent each other.

13. The coil component of claim 11, wherein the first and second lead portions extend from the winding portion in directions perpendicular to each other on the support portion.

14. A coil component, comprising:

a first core including an arcuate channel and a support portion, a core portion protruding from the support portion, and a sidewall portion protruding from the support portion and partially surrounding the core portion, the sidewall portion including first and second sidewalls connected to each other, and surfaces of the first core opposing the first and second sidewalls being open;

a winding-type coil disposed on the first core and at least partially disposed within the arcuate channel; and

a second core attached to the first core.

15. The coil component of claim 14, wherein outer surfaces of the first and second sidewalls are perpendicular to each other.

16. The coil component of claim 14, wherein the coil includes a winding portion, a center of which is coupled to the core portion and first and second lead portions extend from the winding portion in different directions on the support portion.
