GAP LAYER COMPOSITION OF MULTILAYERED POWER INDUCTOR AND MULTILAYERED POWER INDUCTOR INCLUDING GAP LAYER

摘要

PROBLEM TO BE SOLVED: To provide a gap layer composition of a multilayered power inductor and a multilayered power inductor including a gap layer manufactured therefrom.;SOLUTION: The present invention relates to: a multilayered power inductor comprising a body in which a plurality of magnetic layers including inner electrodes are stacked, and a plurality of gap layers, the plurality of gap layers being formed so as not to be in contact with external electrodes formed on both sides of the body; and a gap composition of the multilayered power inductor. In addition, according to the present invention, as the gap composition, tetravalent or tetravalent dielectric oxide is prepared into a paste type and is applied to the gap layer structure. This facilitates the structural design and the thickness control of the gap layer as compared with the case of forming the gap layer in a sheet shape of the related art and can improve DC-bias characteristics by maximally suppressing diffusion with the body.;COPYRIGHT: (C)2013,JPO&INPIT
