Multilayer ceramic capacitor and board having the same mounted thereon
Abstract:
A multilayer ceramic capacitor may include: an active part including a plurality of first and second internal electrodes; upper and lower cover layers; and first and second external electrodes including head parts and band parts. When a thickness of the upper or lower cover layer is defined as C, a width of a margin portion of the ceramic body in a width direction is defined as M, a cross-sectional area of the ceramic body in a width-thickness direction is defined as Ac, a cross-sectional area of the active part in a width-thickness direction in a portion thereof in which the first and second internal electrodes are overlapped with each other in a thickness direction is defined as Aa, and a width of the band part of the first or second external electrode is defined as B, 1.826≦C/M≦4.686, 0.2142≦Aa/Ac≦0.4911, and 0.5050≦C/B≦0.9094 may be satisfied.
