Abstract
Provided are a power inductor including a body, a base disposed in the body, a coil disposed on the base, a first external electrode connected to the coil, the first external electrode being disposed on a side surface of the body, and a second external electrode connected to the first external electrode, the second external electrode being disposed on a bottom surface of the body and a method for manufacturing the same.
Claims19
A power inductor, comprising:
- a body;
- a base disposed in the body;
- a coil disposed on the base;
- a first external electrode connected to the coil, the first external electrode being disposed on first and second surfaces of the body, which are opposite to each other;
- and
- a second external electrode connected to the first external electrode, the second external electrode being disposed on a third surface of the body, which is adjacent to the first and second surfaces.
A power inductor, comprising:
- a body comprising a stepped portion formed on an area of a top surface thereof a base disposed in the body;
- a coil disposed on the base;
- and
- external electrodes connected to the coil, the external electrodes being disposed from first and second surfaces, which are opposite to each other, to upper and lower portions of the body, respectively
- wherein each of the external electrodes has a height less than the stepped portion on the upper portion of the body.
A power inductor, comprising:
- a body;
- a base disposed in the body;
- a coil disposed on the base;
- an external electrode disposed on a surface of the body;
- and
- a connection electrode disposed in the body and connecting the coil to the external electrode.
A method for manufacturing a power inductor, the method comprising:
- forming a coil on at least one base;
- forming a plurality of sheets comprising metal powder and a polymer;
- stacking the plurality of sheets with the base therebetween to press the sheets, and then molding the sheets to form a body;
- forming a second external electrode on a surface of the body so as to be spaced a predetermined distance;
- and
- forming a first external electrode connected to the second external electrode on a side surface of the body.
A method for manufacturing a power inductor, the method comprising:
- forming a coil on at least one base;
- forming a plurality of sheets comprising metal powder and a polymer, in which a hole is formed in a predetermined area thereof;
- stacking the plurality of sheets with the base therebetween, compressing the sheet, and then molding the sheets to form a passing hole exposing a predetermined area of the coil;
- filling the passing hole to form a connection electrode;
- and
- forming an external electrode on a surface of the body and connecting the external electrode to the connection electrode.
