Abstract
An inductor includes a body including a support member, a coil, and an encapsulant, and external electrodes on external surfaces of the body. The coil in the body may be formed so that a plurality of coil patterns are continuously formed, wherein the coil pattern includes first and second coil layers, and the encapsulant extends downward between adjacent coil patterns to be between first coil layers of adjacent coil patterns.
Claims12
An inductor comprising:
- a body including a support member, a coil supported by the support member, and an encapsulant encapsulating the support member and the coil;
- and
- a first external electrode on a first external surface of the body and a second external electrode on a second external surface of the body,
- wherein the coil includes a first plurality of coil patterns on a first surface of the support member and a second plurality of coil patterns on a second surface of the support member opposite the first surface of the support member, each of the first and second plurality of coil patterns including a first coil layer and a second coil layer on the first coil layer,
- the encapsulant contains magnetic powder and fills spaces between adjacent coil patterns among the first and second plurality of coil patterns,
- the encapsulant extends to between adjacent coil patterns to be between first coil layers of adjacent coil patterns,
- the support member includes a via hole and a penetration via which fills the via hole, and
- the penetration via includes an exposed surface which is entirely covered by the first coil layer of at least one of the first or second plurality of coil patterns.
