Abstract
A thin film-type inductor includes a body and a first external electrode and a second external electrode, each disposed on an external surface of the body. The body includes a support member, a first coil, a second coil, a magnetic material surrounding the support member. The first coil is disposed on an upper surface of the support member, and the second coil is disposed on a lower surface of the support member. The support member includes through-hole and a via electrode therein. A portion of one of an upper surface and a lower surface of the via electrode opposes the magnetic material.
Claims18
A thin film-type inductor, comprising:
- a body comprising:
- a support member having a through-hole,
- a first coil disposed on an upper surface of the support member,
- a second coil disposed on a lower surface of the support member, each of the first coil and the second coil including a first end and a second end, and
- a magnetic material surrounding the support member;
- and
- a first external electrode and a second external electrode, disposed on respective external surfaces of the body opposing each other in a length direction,
- wherein the support member includes a via electrode therein,
- a portion of the via electrode overlapping the first end of the first coil and a portion of the via electrode overlapping the first end of the second coil are offset in the length direction such that the first end of the first coil connects on a second side of the center of the via electrode, the second side being opposite the first side in the length direction, and
- the second ends of the first and second coils directly contact a corresponding one of the first and second external electrodes.
