  • Patent number: 10510491
    Abstract: A capacitor component includes a body including a dielectric layer and first and second internal electrodes, alternately disposed in a first direction, and first and second external electrodes, respectively disposed on opposite end surfaces of the body in a second direction, perpendicular to the first direction in the body. An amorphous second phase is disposed at an interface between the first and second internal electrodes and the dielectric layer, and s/e is between 0.02 and 0.07, where s is a total length of the amorphous second phase disposed in a boundary line between the first or second internal electrode and the dielectric layer in the second direction and e is a length of the first or second internal electrode in the second direction.

  • Patent number: 10490353
    Abstract: A multilayer ceramic capacitor includes a ceramic body with first and second internal electrodes facing each other and dielectric layers interposed therebetween. First and second external electrodes are on external surfaces of the ceramic body and electrically connected to the first and second internal electrodes, respectively. A dielectric layer includes dielectric grains including, respectively, first regions in which dysprosium (Dy) is not present and second regions surrounding the first regions. Where a shortest distance between boundaries of the first regions (in which dysprosium (Dy) is not present) of two of the dielectric grains is “L,” the concentration of dysprosium (Dy) in a region within ±0.2 L from a halfway point between the boundaries is lower than that of dysprosium (Dy) in the second regions.

  • Publication number: 20190244757
    Abstract: A capacitor component includes a body in which a dielectric layer and an internal electrode are alternately stacked, and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer includes a composite layer including a dielectric material powder and a metallic particle and first and second protective layers including a dielectric material powder and spaced apart by the composite layer. A thickness of each of the first and second protective layers is equal to or greater than ? of a thickness of the dielectric layer.
