Abstract
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.
Claims8
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.
