Abstract:
A dielectric ceramic composition for multilayer ceramic capacitor (MLCC) includes a first component of 91 to 98 wt % and a second component of 2 to 9 wt %, wherein the first component includes a main component BaTiO3 of 94 to 98 wt %, a first subcomponent of 0.5 to 2 wt % including a glass powder having a network structure, and a second subcomponent of 1 to 4 wt % including at least one of MgO, Cr2O3 and Mn3O4, and the second component includes (Ba1-y-xCaySrx)(ZryTi1-y)O3, and x satisfies 0.2≦x≦0.8 and y satisfies 0.03≦y≦0.15.
