Multilayer ceramic capacitor and board having the same mounted thereon

A board having a multilayer ceramic capacitor mounted thereon, the board comprising:

• a printed circuit board having first and second electrode pads disposed on the printed circuit board;
• and
• the multilayer ceramic capacitor mounted on the printed circuit board,
• wherein the multilayer ceramic capacitor includes:
• a ceramic body in which a plurality of dielectric layers having an average thickness of 0.2 μm to 2.0 μm are stacked;
• an active layer including first and second internal electrodes alternately exposed to end surfaces of the ceramic body, at least one of the dielectric layers being interposed between the first and second internal electrodes;
• an upper cover layer disposed on the active layer;
• a lower cover layer disposed below the active layer and being thicker than the upper cover layer;
• and
• first and second external electrodes covering the end surfaces of the ceramic body,
• at least one edge of the ceramic body in length, width, and thickness directions being rounded, and when a radius of curvature of the edge is defined as R and a thickness of the upper cover layer is defined as D, R/D being in a range of 0.1 to 0.7 (0.1≦R/D≦0.7).
