    摘要： A multilayer ceramic capacitor includes: a ceramic body in which dielectric layers and first and second internal electrodes are alternately stacked; and first and second external electrodes formed on an outer surface of the ceramic body and electrically connected to the first and second internal electrodes, respectively. In a microstructure of the dielectric layer, dielectric grains are divided by a dielectric grain size into sections each having an interval of 50 nm, respectively, a fraction of the dielectric grains in each of the sections within a range of 50 nm to 450 nm is within a range of 0.025 to 0.20, and a thickness of the dielectric layer is 0.8 μm or less.

    摘要： A multilayer ceramic capacitor includes a body including first and second dielectric layers and having first to sixth surfaces; a second internal electrode disposed on the second dielectric layer to face the first internal electrode with the first or second dielectric layer interposed therebetween, exposed to the fourth, fifth, and sixth surfaces, and disposed to be spaced apart from the third surface by a second space; a first dielectric pattern disposed in at least a portion of the first space; a second dielectric pattern disposed in at least a portion of the second space; a side insulating layer disposed on the fifth and sixth surfaces; a first external electrode disposed on the third surface; and a second external electrode disposed on the fourth surface, in which the first and second dielectric patterns have a color different from the first and second dielectric layers.
