Abstract
Official abstract text for this publication.
An inductor includes: a body having a coil including lead out portions disposed therein, and external electrodes connected to the lead out portions, at least partially disposed in the body, and exposed to a first surface of the body, thereby miniaturizing an inductor, securing Q characteristics, and improving inductance.
First claim
Opening claim text (preview).
What is claimed is: 1. An inductor, comprising: a body including a coil disposed therein, the coil including first and second lead out portions extended toward a first surface opposing a second surface and connecting a third surface to a fourth surface; and external electrodes, disposed at least partially in the body, including a first external electrode connected to the first lead out portion and exposed to the first and third surfaces of the body, and a second external electrode connected to the second lead out portion and exposed to the first and fourth surfaces of the body, wherein each of the external electrodes include a conductive layer and a plating layer formed on a surface of the conductive layer, wherein a portion of the respective plating layers of the external electrodes in the directions of the third and fourth surfaces of the body, respectively, have an outer surface aligned with the third and fourth surfaces of the body, respectively. 2. The inductor of claim 1 , wherein the external electrodes have an L shape. 3. The inductor of claim 1 , wherein a portion of the respective conductive layers of the external electrodes in the direction of the first surface of the body have an outer surface aligned with the first surface of the body. 4. The inductor of claim 1 , wherein the external electrodes are spaced apart from the coil. 5. The inductor of claim 1 , wherein the first surface is perpendicular to a direction in which the coil is wound. 6. A multilayer inductor, comprising: a body including a plurality of stacked insulating layers having conductor patterns formed thereon; and first and second external electrodes disposed at least partially in the body and exposed to a first surface of the body, wherein at least one of the conductor patterns includes a first lead out portion connected to the first external electrode and at least one of the conductor patterns includes a second lead out portion connected to the second external electrode, wherein the first and second external electrodes each include a conductive layer and a plating layer formed on a surface of the conductive layer, wherein a portion of the respective plating layers of the first and second external electrodes in the directions of second and third surfaces of the body, respectively, have an outer surface aligned with the second and third surfaces of the body, respectively. 7. The multilayer inductor of claim 6 , wherein the body further includes a cover layer in at least one of the upper or lower portion of the body in the stacking direction. 8. The multilayer inductor of claim 6 , wherein a portion of the conductive layers of the first and second external electrodes are aligned with the first surface of the body and a portion of the plating layers at the first surface are external to the body.
