Abstract
A coil electronic component including: a substrate; a coil pattern disposed on at least one surface of the substrate; a body filling at least a core area of the coil pattern and containing a magnetic material; and a magnetic flux controller disposed at an outer surface of the body to correspond to the core area and containing a magnetic material which has a permittivity value higher than that of the magnetic material of the body.
Claims20
A coil electronic component, comprising:
- a substrate;
- a coil pattern disposed on at least one surface of the substrate;
- a body filling at least a core area of the coil pattern and containing a magnetic material;
- and
- a magnetic flux controller disposed at an outer surface of the body and corresponding to the core area, the magnetic flux controller containing a magnetic material which has a permittivity value higher than that of the magnetic material of the body,
- wherein the magnetic flux controller has a surface area smaller than that of the core area such that the magnetic flux controller is disposed at the outer surface of the body partly, and
- wherein when viewing the coil electronic component from a side in a width-length direction thereof, a width of the magnetic flux controller is smaller than that of the core area.

A coil electronic component, comprising:
- a substrate;
- at least one coil pattern disposed on upper and lower surfaces of the substrate;
- a body filling a core area of the coil pattern and having a first magnetic material, the core area being in a center of the body;
- external electrodes attached to side surfaces of the body and electrically connected to the coil patterns;
- and
- a second magnetic material grooved into the body at a center area of an outer surface of the body to correspond to the core area, the second magnetic material having a permittivity value 1.5 times or higher than that of the first magnetic material,
- wherein the magnetic flux controller has a surface area smaller than that of the core area, and
- wherein when viewing the coil electronic component from a side in a width-length direction thereof, a width of the center area, into which the second magnetic material is filled, is smaller than that of the core area.
