  • Patent number: 9041506
    Abstract: Disclosed herein are a multilayer power inductor and a method of manufacturing the same. The multilayer power inductor includes a multilayer body formed by multi-layering a plurality of body sheets; a coil portion including internal electrode patterns that are respectively formed on the plurality of body sheets; and external electrodes that are disposed on lateral surfaces of the multilayer body and are electrically connected to both ends of the coil portion, wherein a space portion is formed in the internal electrode pattern to correspond to contraction of the plurality of body sheet. The multilayer power inductor relieves internal stress generated in a product through the space portion so as to prevent the body sheet from being magnetized due to the internal stress, thereby preventing a reduction in inductance. The multilayer inductor may also be manufactured by using conventional manufacturing processes themselves without any influence on the productivity of a product.

  • Patent number: 8890647
    Abstract: 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.
