  • Patent number: 9685272
    Abstract: A multilayer ceramic capacitor and a board having the same are provided. The multilayer ceramic capacitor includes three external electrodes including a conductive layer, a nickel plating layer, and a tin plating layer sequentially stacked on a mounting surface of the ceramic body, and spaced apart from each other. When an outermost portion of a lead-out portion of an internal electrode exposed to the mounting surface is P, a total thickness of the conductive layer, the nickel plating layer, and the tin plating layer in a normal line direction of the conductive layer from P is a, a thickness of the conductive layer in the normal line direction of the conductive layer from P is b, and a sum of pore heights of pores existing in the conductive layer in the normal line direction of the conductive layer from P is bp, (b?bp)/a satisfies 0.264?(b?bp)/a?0.638.
