Disclosed herein is a multilayer inductor. The multilayer inductor according to an exemplary embodiment of the present invention includes a laminate on which a plurality of body sheets are multilayered; a coil part configured to have internal electrode patterns formed on the body sheet; a first gap made of a non-magnetic material located between the multilayered body sheets; a second gap made of a dielectric material located between the multilayered body sheets and located on a layer different from the first gap; and external electrodes formed on both surfaces of the laminate and electrically connected with both ends of the coil part. By this configuration, the exemplary embodiment of the present invention can remarkably improve DC biased characteristics without reducing breaking strength of the inductor.

Multilayer inductor

Disclosed herein is a filter chip element including a ferrite substrate, internal coil patterns formed on the ferrite substrate; and a ferrite composite layer filled between the internal coil patterns formed on the ferrite substrate, wherein the ferrite composite layer includes foaming resin, thereby increasing magnetic permeability and a Q value which are important characteristics of a filter chip element for noise prevention among electromagnetic shielding components.

Filter chip element and method of preparing the same

There is provided a multilayer type inductor, including: an inductor main body; a coil part having conductive circuits and conductive vias formed in the inductor main body; and external electrodes formed on both ends of the inductor main body, wherein in the inductor main body, at least parts around the conductive circuits and the conductive vias are formed of a ferrite material or a non-magnetic material.

Multilayer type inductor and method of manufacturing the same

The present invention relates to a chip inductor including: a metal-polymer composite in which metal particles and polymer are mixed; a wiring pattern provided inside the metal-polymer composite to form a coil; an external electrode provided in a portion of an outer peripheral surface of the metal-polymer composite; and an insulating portion provided between the metal-polymer composite and the wiring pattern and between the metal-polymer composite and the external electrode, and a method for manufacturing the same.

Chip inductor and method for manufacturing the same

There is provided a laminated inductor including: a body where a plurality of magnetic layers are laminated; a coil part formed on the magnetic layers, the coil part including a plurality of conductor patterns and a plurality of conductive vias; first and second external electrodes formed on an outer surface of the body to connect to both ends of the coil part, respectively; and a non-magnetic conductor formed on at least one of the magnetic layers so as to relax magnetic saturation caused by direct current flowing through the coil part. The laminated inductor employs the non-magnetic conductor as a non-magnetic gap to be simplified in a manufacturing process and effectively improved in DC superposition characteristics.
