Multilayer ceramic capacitor and board having the same

摘要

A multilayer ceramic capacitor may include: three external electrodes disposed on amounting surface of a ceramic body to be spaced apart from one another. When a thickness of an active layer including a plurality of first and second internal electrodes disposed therein is defined as AT, and a gap between a first or second lead part of the first internal electrode and a third lead part of the second internal electrode is defined as LG, the following Equation may be satisfied: 0.00044≦LG*log [1/AT]≦0.00150.

1. A multilayer ceramic capacitor comprising:
a ceramic body including a plurality of dielectric layers stacked therein in a width direction; an active layer including a plurality of first and second internal electrodes alternately disposed with the respective dielectric layers interposed therebetween; first and second lead parts formed in the first internal electrode to be extended and exposed to a mounting surface of the ceramic body, and disposed to be spaced apart from each other in a length direction of the ceramic body; a third lead part formed in the second internal electrode to be extended and exposed to the mounting surface of the ceramic body, and disposed between the first and second lead parts; first and second external electrodes disposed on the mounting surface of the ceramic body to be spaced apart from each other in the length direction of the ceramic body, and connected to the first and second lead parts, respectively; and a third external electrode disposed between the first and second external electrodes, extended from the mounting surface of the ceramic body to portions of both side surfaces of the ceramic body in the width direction, and connected to the third lead part, wherein when a thickness of the active layer is defined as AT, and a gap between the first or second lead part and the third lead part is defined as LG, the following Equation is satisfied: 0.00044≦LG*log[1/AT]≦0.00150.
