Abstract:
1. A laminated chip electronic component for mounting on a printed circuit board (PCB), the laminated chip electronic component comprising: a ceramic body including internal electrodes and dielectric layers; external electrodes formed to cover both end portions of the ceramic body in a length direction; an active layer in which the internal electrodes are disposed in an opposing manner, with the dielectric layers interposed therebetween, to form capacitance; and upper and lower cover layers formed on upper and lower portions of the active layer in a thickness direction, the lower cover layer having a thickness greater than that of the upper cover layer and being adjacent to the printed circuit board when mounted thereon; wherein when half of a thickness of the ceramic body is defined as A, a thickness of the lower cover layer is defined as B, half of a thickness of the active layer is defined as C, and a thickness of the upper cover layer is defined as D: the thickness (D) of the upper cover layer satisfies a range of D≧4 μm, a ratio (B+C)/A in which a central portion of the active layer deviates from a central portion of the ceramic body satisfies a range of 1.063≦(B+C)/A≦1.745, the lower cover layer includes an identification layer having a color distinguished from that of the upper cover layer, and the identification layer has a thickness ranging from 30 μm to a thickness equal to that of the lower cover layer.
