Abstract
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 length of the ceramic body is defined as L, and a width of an active region including a plurality of internal electrodes disposed therein in a width direction of the ceramic body is defined as A, A/L is in a range of 0.64 to 1.14 (0.64≦A/L≦1.14).
Claims23
A multilayer ceramic capacitor comprising:
- a ceramic body including a plurality of dielectric layers stacked therein in a width direction thereof;
- an active region including a plurality of first and second internal electrodes alternately disposed, having one of the dielectric layers interposed therebetween;
- first and second lead portions extending from the first internal electrode so as to be 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 portion extending from the second internal electrode so as to be exposed to the mounting surface of the ceramic body, and disposed between the first and second lead portions;
- 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 thereof, and connected to the first and second lead portions, respectively;
- and
- a third external electrode disposed on the mounting surface of the ceramic body between the first and second external electrodes, and connected to the third lead portion;
- wherein A/L is in a range of 0.64 to 1.14 (0.64≦A/L≦1.14), in which L is a length of the ceramic body determined in the length direction and A is a width of the active region determined in the width direction, and
- W/L is in a range of 0.7 to 1.2 (0.7≦W/L≦1.2), in which W is a width of the ceramic body determined in the width direction.
