Dielectric Ceramic Composition and Multilayer Ceramic Capacitor Comprising the Same

A multilayer ceramic capacitor, comprising:

• a ceramic body comprising dielectric layers and first and second internal electrodes disposed to face each other with a respective dielectric layer interposed therebetween;
• and
• a first external electrode and a second external electrode disposed on external surfaces of the ceramic body, the first external electrode being electrically connected to the first internal electrode and the second external electrode being electrically connected to the second internal electrode,
• wherein the dielectric layers comprise dielectric grains comprising a dielectric ceramic composition, and
• the dielectric ceramic composition comprises a base material main ingredient including at least one compound selected from the group consisting of BaTiO3, (Ba1-xCax) (Ti1-yCay)O3 (where 0≤x≤0.3, 0≤y≤0.1), (Ba1-xCax) (Ti1-yZry)O3 (where 0≤x≤0.3, 0≤y≤0.5), and Ba (Ti1-yZry)O3 (where 0<y≤0.5), and an accessory ingredient, the accessory ingredient comprising dysprosium (Dy) and niobium (Nb) as first accessory ingredients, and
• wherein a total content of the Dy and Nb is less than or equal to 1.5 mol, based on 100 mol of Ti of the base material main ingredient, and
• wherein a thickness of at least one of the first and second internal electrodes is 0.4 μm or less.
