Multilayer ceramic electronic component and mounting board therefor

A multilayer ceramic electronic component comprising:

• a ceramic body having a hexahedral shape, including dielectric layers, and satisfying T/W>1.0 when a length of the ceramic body is defined as L, a width of a lower surface of the ceramic body is defined as W, and a thickness of the ceramic body is defined as T;
• and
• first and second internal electrodes stacked in the ceramic body so as to face each other, having the respective dielectric layers interposed therebetween,
• wherein a cross-section of the ceramic body in a width-thickness direction (W-T) has a trapezoidal shape.

A mounting board for a multilayer ceramic electronic component, the mounting board comprising:

• a printed circuit board having first and second electrode pads disposed thereon;
• and
• a multilayer ceramic electronic component mounted on the printed circuit board,
• wherein the multilayer ceramic electronic component includes:
• a ceramic body having a hexahedral shape, including dielectric layers, and satisfying T/W>1.0 when a length of the ceramic body is defined as L, a width of a lower surface of the ceramic body is defined as W, and a thickness of the ceramic body is defined as T;
• and first and second internal electrodes stacked in the ceramic body so as to face each other, having the respective dielectric layers interposed therebetween,
• the ceramic body includes an active layer, corresponding to a capacitance formation part contributing to capacitance formation, and cover layers, corresponding to non-capacitance formation parts, provided on at least one of upper and lower surfaces of the active layer, and
• in a case in which the active layer is divided into three regions in a thickness direction of the ceramic body, when an average thickness of the internal electrodes in an upper region and an average thickness of the internal electrodes in a lower region, based on a central region among the three regions, are defined as ta and tb, respectively, 0.751≦ta/tb≦0.913 is satisfied.
