Abstract
A multilayer ceramic capacitor includes a ceramic body in which a plurality of dielectric layers are layered in a width direction, an active part including a plurality of first and second internal electrodes alternately exposed to opposing end surfaces of the ceramic body with the dielectric layer interposed therebetween to form capacitance, an upper cover part provided on an upper surface of the active part, a lower cover part provided on a lower surface of the active part and having a thickness greater than that of the upper cover part, and first and second external electrodes formed to cover opposing end surfaces of the ceramic body, wherein a ratio of the cube root of the volume of the active part to the thickness of the lower cover part is between 1.4 and 8.8.
