Claims14
A power inductor, comprising:
- a body comprising a metal powder;
- at least one substrate provided inside the body;
- at least one coil pattern provided on at least one surface of the substrate;
- and
- an insulation layer formed on the coil pattern for insulation of the coil pattern and the body, wherein the insulation layer is formed of parylene;
- wherein the insulation layer is filled between the coil patterns and formed on an upper portion of the coil patterns and a side surface of the coil patterns with a uniform thickness, wherein the insulation layer has a thickness of 3 μm to 100 μm;
- and
- wherein the metal powder has a surface coated with a first insulator formed of metal oxide, and a second insulator formed of parylene, wherein the second insulator is coated in a thickness of approximately 1 um to approximately 10 um.
