Abstract

A coil electronic component includes: a body; first and second external electrodes disposed on opposite surfaces of the body in a first direction parallel to a mounting surface of the body; a support member disposed in a second direction, perpendicular to the mounting surface of the body and including a protrusion portion extending in the second direction; and a coil disposed on at least one surface of the support member.

Claims

1. A coil electronic component, comprising:

a body;

first and second external electrodes disposed on opposite surfaces of the body in a first direction parallel to a mounting surface of the body;

a support member disposed in a second direction perpendicular to the mounting surface of the body and including a protrusion portion extending in the second direction; and

a coil disposed on at least one surface of the support member.

2. The coil electronic component of claim 1, wherein the protrusion portion is at least partially exposed from the body.

3. The coil electronic component of claim 1, wherein

the protrusion portion is at least partially exposed on a surface of the body opposite the mounting surface.

4. The coil electronic component of claim 3, wherein the protrusion portion is offset from the center of the surface including the exposed protrusion portion in the first direction.

5. The coil electronic component of claim 3, wherein the surface including the exposed protrusion portion is a diced surface.

6. The coil electronic component of claim 1, wherein a dimension of the body in a third direction perpendicular to the first and second directions is equal to a dimension of the body in the second direction.

7. An electronic circuit, comprising:

a circuit board having a first surface including first and second terminals; and

a coil electronic component disposed on the circuit board,

wherein the coil electronic component includes

a body;

first and second external electrodes disposed on opposite surfaces of the body in a first direction parallel to a mounting surface of the body;

a support member disposed in a second direction, perpendicular to the mounting surface of the body and including a protrusion portion extending in the second direction; and

a coil disposed on at least one surface of the support member.

8. The electronic circuit of claim 7, wherein the protrusion portion is at least partially exposed from the body.

9. The electronic circuit of claim 7, wherein

the protrusion portion is at least partially exposed on a surface of the body opposite the mounting surface.

10. The electronic circuit of claim 9, wherein the protrusion portion is offset from the center of the surface including the exposed protrusion portion in the first direction.

11. The electronic circuit of claim 9, wherein the fourth including the exposed protrusion portion is a diced surface.

12. The electronic circuit of claim 7, wherein a dimension of the body in a third direction perpendicular to the first and second directions is equal to a dimension of the body in the second direction.
