Abstract
Disclosed are a power inductor and a method of manufacturing the same. The power inductor includes a body, a coil pattern provided in the body, an external electrode disposed on at least one surface of the body and extending to at least the other surface of the body, which is adjacent thereto, and a coupling layer provided between the body and an extended area of the external electrode.
Claims11
A power inductor comprising:
- a body having multiple surfaces;
- a coil pattern provided in the body;
- a surface insulation layer disposed on at least one area of a surface of the body;
- an external electrode disposed on at least one surface of the body and extending to at least another surface of the body, which is adjacent to the at least one surface of the body;
- and
- a coupling layer provided between the body and an extended area of the external electrode,
- wherein the coupling layer is disposed between the surface insulation layer and the extended area of the external electrode.
4 more elements
A method of manufacturing a power inductor, the method comprising:
- preparing a body in which a coil pattern is formed;
- forming a surface insulation layer on a surface of the body;
- forming a coupling layer on a predetermined area on the surface insulation layer;
- removing a portion of the coupling layer and the surface insulation layer to expose the coil pattern;
- and
- forming an external electrode on at least one surface of the body so that the external electrode is connected to the coil pattern.
