摘要:
Disclosed herein are a multilayered power inductor including a magnetic layer having a structure in which a metal magnetic powder is distributed on a glass substrate, a composition for the magnetic layer, and a method for preparing a multilayered power inductor. According to an exemplary embodiment of the present invention, the multilayered power inductor including a magnetic layer obtained by mixing the metal magnetic powder having high Ms with the glass substrate has excellent bias characteristics having small variations in capacity even when high current is applied. In addition, the exemplary embodiment of the present invention can use Cu as an inner electrode, instead of an expensive precious metal Ag.
