Abstract
A coil component includes a body, including a coil and a support member supporting the coil, and an external electrode disposed on an external surface of the body. The coil component includes a machined surface formed on a boundary surface between a portion of the support member, removed in the vicinity of a junction portion between the external electrode and the coil, and the remainder of the support member. A cavity, from which the portion of the support member has been removed, is filled with a magnetic material, or an insulating layer is disposed in the cavity.
Claims29
A coil component comprising:
- a body including a coil and a magnetic material, the coil including at least one lead portion;
- and
- an external electrode disposed on at least a portion of an external surface of the body and having an internal surface contacting and electrically connected to the coil,
- wherein a support member is disposed in the body to support the coil, and at least a portion of a surface of the support member facing toward the internal surface of the external electrode includes a machined surface.
A coil component comprising:
- a body including a coil, the coil including a coil body and at least one lead portion connected to the coil body;
- and
- an external electrode disposed on at least a portion of an external surface of the body and electrically connected to the at least one lead portion of the coil,
- wherein the body further includes a support member, the coil is disposed on one surface of the support member, and an outer boundary surface of the support member is spaced apart from a junction portion between the external electrode and the at least one lead portion at a predetermined interval.
A coil component comprising:
- a support member having a surface with a coil disposed thereon;
- a body formed of a magnetic material, wherein the support member and coil are disposed within the body;
- and
- an external electrode disposed on an external surface of the body and contacting a lead portion of the coil,
- wherein a thickness of the support member, measured orthogonally to the surface of the support member having the coil disposed thereon, is smaller at a position closer to the external electrode than at a position further from the external electrode.
A coil component comprising:
- a support member having a coil disposed thereon;
- a body formed of a magnetic material, wherein the support member and coil are disposed within the body;
- and
- an external electrode disposed on an external surface of the body and contacting a lead portion of the coil,
- wherein a surface of the support member facing the external surface of the body having the external electrode includes at least two protrusions separate from each other and extending towards the external surface of the body.
A coil component comprising:
- a support member having a coil disposed thereon;
- a body formed of a magnetic material, wherein the support member and coil are disposed within the body;
- and
- an external electrode disposed on an external surface of the body and contacting a lead portion of the coil,
- wherein a surface of the support member facing the external surface of the body having the external electrode is coplanar with an outermost coil pattern of the coil body.
