Abstract

A coil component includes a core including a winding portion and a flange portion extending from a first end of the winding portion, a coil wound around the winding portion, a lead formed at the flange portion, and a cover coupled to the flange portion and covering at least a portion of the coil.

Claims

1. A coil component, comprising:

a core including a winding portion and a flange portion extending from a first end of the winding portion;

a coil wound around the winding portion;

a lead formed at the flange portion; and

a cover coupled to the flange portion and covering at least a portion of the coil,

wherein the cover covers one side portion and an upper portion of the coil,

the portion of the cover covering the upper portion of the coil includes an opening,

an area of the opening is greater than that of a longitudinal cross section of the winding portion,

the opening is adhered to a second end opposite the first end of the winding portion such that the winding portion contacts the opening at a region of the opening opposite to the one side portion of the coil covered by the cover and does not contact a region of the opening adjacent to any side portion of the coil covered by the cover,

at least a portion of the lead is embedded in the flange portion,

the lead is bent to one side of the coil, and

the lead is bent to cover the portion of the cover covering the upper portion of the coil.

2. The coil component of claim 1, wherein a center of the opening is spaced apart from a center of the winding portion.

3. The coil component of claim 1, wherein the coil has at least one drawing portion and the drawing portion is connected to the lead.

4. The coil component of claim 1, wherein the core includes magnetic powder particles and a thermosetting resin.

5. The coil component of claim 4, wherein the thermosetting resin is epoxy or polyimide.

6. The coil component of claim 1, wherein the winding portion is disposed to be perpendicular with respect to the flange portion.
