  • Publication number: 20140126109
    Abstract: There is provided a multilayered ceramic electronic component including: a ceramic body including dielectric layers; internal electrodes disposed to face each other, having the dielectric layers therebetween; and external electrodes formed on outer surfaces of the ceramic body and electrically connected to the internal electrodes, wherein the internal electrodes include a first ceramic powder formed of barium titanate (BaTiO3) and having a particle diameter corresponding to 70% to 100% of a thickness of the respective internal electrodes. According to the present invention, disconnection generated due to differences in contraction and extension between the internal electrodes and the dielectric layers may be improved, whereby the multilayered ceramic electronic component having excellent capacitance and reliability may be implemented.

  • Patent number: 8587920
    Abstract: Disclosed herein are a multilayer ceramic electronic component and a method for manufacturing the same. The multilayer ceramic electronic component includes a multilayer body in which dielectric layers and internal electrode layers are alternately stacked and external electrodes, wherein a portion in the internal electrode layers positioned in a marginal portion in which vertically neighboring internal electrode layers in the multilayer body is not overlapped with each other has a thickness thicker than that of a portion of the internal electrode layer positioned in an overlapped portion in which the vertically neighboring internal electrode layers are overlapped with each other, such that an accumulated stepped height difference in the marginal portion is reduced.
