Abstract

There is provided a multilayer inductor including: an inductor body formed of a material including metal powder particles, a ferrite, and a polymer resin; a coil part having a conductive circuit and a conductive via formed in the inductor body; and external electrodes formed on ends of the inductor body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0046562 filed with the Korean Intellectual Property Office on May 2, 2012, the disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a multilayer inductor and a manufacturing method thereof. Background technique [0004] Electronic components using ceramic materials provided as representative ones include capacitors, inductors, piezoelectric elements, varistors, thermistors, and the like. [0005] Among these ceramic electronic components, inductors as well as resistors and capacitors are main passive elements constituting electronic device circuits, and can be used as a resonance circuit for removing noise or constituting an inductor-capacitor (LC). [0006] Inductors can be fabricated by winding or printing a coil on a ferrite core and forming electrodes at both ends thereof, or by printin...
