Title:
STACKED INDUCTOR USING MAGNETIC SHEETS, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2010/126332
Kind Code:
A2
Abstract:
The present invention relates to a stacked power inductor having high direct current superimposition characteristics and high frequency characteristics, and in particular, to a stacked power inductor to which a magnetic sheet filled with soft magnetic metal powder and a magnetic core are applied as a magnetic body. A technical aim of the present invention is to provide a stacked power inductor having high inductance and direct current superimposition characteristics, and a method for manufacturing same. In order to achieve the aim, a method for manufacturing a stacked inductor using magnetic sheets comprises: stacking a plurality of layers of magnetic sheets having conductive circuits formed on the surfaces thereof; forming a terminal part on an outermost portion; forming a coil-shaped circuit through conductively connecting the conductive circuits and the terminal part through a via hole; and inserting a magnetic core into the coil-shaped circuit.
