MULTILAYER CERAMIC ELECTRONIC COMPONENT AND BOARD FOR MOUNTING THE SAME

摘要

A multilayer ceramic electronic component includes a ceramic main body including dielectric layers and satisfying T/W>1.0 when W and T are width and thickness, respectively; and first and second internal electrodes stacked in the ceramic main body and facing each other with the dielectric layer interposed therebetween, the ceramic main body including an active layer corresponding to a capacitance forming portion contributing to capacitance formation and a cover layer corresponding to a non-capacitance forming portion provided on at least one of uppermost and lowermost surfaces of the active layer, and when the active layer is divided into three regions in a direction in which the first and second internal electrodes are stacked, an average width of internal electrodes in a central region of the three regions is Wa, and an average width of internal electrodes in upper and lower regions of the three regions is Wb, 0.920≦Wb/Wa≦0.998 is satisfied.
