    Abstract: A multilayer ceramic capacitor includes a body including a dielectric layer and first and second internal electrodes stacked in a first direction and having first and second surfaces opposing each other in the first direction, third and fourth surfaces opposing each other in a second direction, and fifth and sixth surfaces opposing each other in a third direction, and first and second external electrodes disposed on the third and fourth surfaces of the body, respectively, and connected to the first and second internal electrodes, respectively. The first and second external electrodes each include a central portion disposed in a center of each of the third and fourth surfaces and an outer portion disposed outside the central portion. T1>T2>T3, in which T1 and T3 are maximum value and minimum value of a thickness of the central portion, respectively, and T2 is a maximum value of a thickness of the outer portion.

    Abstract: A multilayer ceramic electronic component includes: a ceramic body including a dielectric layer having a main component represented by (Ba1-xCax) (Ti1-y(Zr, Hf)y)O3 (where, 0≤x≤1, 0≤y≤0.5), and including first and second internal electrodes alternately stacked with the dielectric layer interposed therebetween; a first external electrode connected to the first internal electrode; and a second external electrode connected to the second internal electrode, wherein at least one of the dielectric layer and the internal electrode includes Sn or Dy. If Sn, an average content of Sn at an interface between the dielectric layer and the internal electrode is within a range of 5 at % or more and 20 at % or less. If Dy, an average content of Dy at an interface between the dielectric layer and the internal electrode is within a range of 1 at % or more and 5 at % or less.
