Abstract
A coil component includes a body; a coil portion disposed in the body and including a lead-out pattern; an external electrode disposed on a first surface of the body; and a plurality of connection vias disposed in the body, connecting the external electrode to the lead-out pattern, and integrated with each other, wherein, in each of the plurality of connection vias, a size of an end surface area of a lower portion adjacent to the external electrode is different from a size of an end surface area of an upper portion adjacent to the lead-out pattern.
Claims15
A coil component, comprising:
- a body;
- a coil portion disposed in the body and including a lead-out pattern;
- an external electrode disposed on a first surface of the body;
- and
- a plurality of connection vias disposed in the body, connecting the external electrode to the lead-out pattern, and integrated with each other,
- wherein, in each of the plurality of connection vias, a size of an end surface area of a lower portion relatively proximate to the external electrode is different from a size of an end surface area of an upper portion relatively proximate to the lead-out pattern.
A coil component, comprising:
- a body having a first surface;
- a support substrate disposed in the body;
- a coil portion including first and second lead-out patterns disposed on the first surface of the support substrate opposing the first surface of the body;
- first and second external electrodes disposed on the first surface of the body and spaced apart from each other;
- a first connection electrode disposed in the body, connecting the first lead-out pattern to the first external electrode, and integrally formed between the first lead-out pattern and the first external electrode;
- and
- a second connection electrode disposed in the body, connecting the second lead-out pattern to the second external electrode, and integrally formed between the second lead-out pattern and the second external electrode,
- wherein, when an end surface area parallel to the first surface of the body is defined as a cross-sectional area, at least one of the first and second connection electrodes includes an anchor portion having a cross-sectional area larger than a cross-sectional area of the other region.
A coil component, comprising:
- a support substrate having a first surface;
- a coil pattern disposed on the first surface and having a lead-out portion;
- a body encapsulating the support substrate and the coil pattern, the body having a first surface parallel to the first surface of the support substrate;
- an external electrode disposed on the first surface of the body;
- and
- stacked connection vias disposed between the lead-out portion and the external electrode, each connection via having a cross-section tapering from the lead-out portion to the first surface of the body.
