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.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2014-0023639 filed on February 27, 2014 and Korean Patent Application No. 10-2014-0143390 filed on October 22, 2014 at the Korean Intellectual Property Office and rights, the disclosures of these Korean patent applications are hereby incorporated by reference. technical field [0002] The present disclosure relates to a multilayer ceramic capacitor and a board having the same. Background technique [0003] As electronic components using ceramic materials, capacitors, inductors, piezoelectric elements, varistors, thermistors, and the like can be used. [0004] Among these ceramic electronic components, multilayer ceramic capacitors (MLCCs) have advantages such as small size, high capacitance, easy mounting, and the like. [0005] Multilayer ceramic capacitors are chip capacitors mounted on the boards of various electronic products such as computers, personal digital assistants (PDAs), and cellular ...
