Magnetic layer composition, multilayer type coil component, and method for manufacturing the same

摘要

Disclosed herein are a multilayer type inductor including a magnetic layer composition including NiZn ferrite, a multilayer type coil component including a magnetic layer prepared therefrom, and a method for manufacturing the same.;According to the present invention, a copper electrode can be used as an internal electrode of a multilayer type coil product, by including NiZn ferrite in the magnetic layer. As copper is used for the internal electrode, material costs can be significantly reduced. Furthermore, the present invention can improve the maximum saturation magnetization value against the NiCuZn ferrite by about 10%, due to exclusion of Cu having weak magnetism, and can be more desirably used in a product employing high current.
