1. A multi-layered ceramic electronic component comprising:
a ceramic body including a dielectric layer, and a plurality of first and second internal electrodes opposing each other with the dielectric layer interposed therebetween, and including first and second surfaces opposing each other in a first direction, third and fourth surfaces connected to the first and second surfaces and opposing each other in a second direction, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other in a third direction; and
first and second external electrodes arranged outside of the ceramic body and electrically connected to the first and second internal electrodes,
wherein the dielectric layer comprises a dielectric ceramic composition containing:
a base material represented by (Ba1-xCax)TiO3 (0<x≤0.09) as a main component,
a first accessory component of yttrium (Y),
a second accessory component of magnesium (Mg),
a third accessory component of barium (Ba) or zirconium (Zr), or a mixture thereof in an amount of 1.5 moles or more and 3.5 moles or less, based on 100 moles of Ti,
a fourth accessory component of manganese (Mn), nickel (Ni), tungsten (W), vanadium (V), or iron (Fe), or mixtures thereof,
a fifth accessory component of silicon (Si), and
wherein the dielectric ceramic composition comprises Si in an amount 1.2 moles or more and 2.2 moles or less, based on 100 moles of Ti.
