  • Patent number: 8842413
    Abstract: There is provided a multilayered ceramic electronic component having a reduced thickness and exhibiting hermetic sealing. In multilayered ceramic electronic component, an external electrode includes two layers, that is, first and second layers, and the first and second layers contain glass with different compositions, respectively. Therefore, the multilayered ceramic electronic component having high reliability, such as strong adhesion between the external electrode and the internal electrode, prevention of glass exudation, or the like, may be obtained.

  • Publication number: 20120162856
    Abstract: There are provided a conductive paste composition for a termination electrode, and a multilayer ceramic capacitor including the same and a manufacturing method thereof. The conductive paste composition includes 100 parts by weight of conductive metal powder and 0.1 to 10 parts by weight of ceramic powder having an average particle size of 50 to 500 nm. The conductive paste composition described above may achieve a high firing density even in the case that it is used in the manufacturing of a thin film, and inhibit the occurrence of blisters, a delamination failure of the termination electrode during calcination of the electrode, thereby producing a compact and thin film.
