    摘要： There is provided a multilayer ceramic capacitor including: a ceramic main body having first and second side faces opposed to each other and third and fourth side faces connecting the first and second side faces; a plurality of inner electrodes formed within the ceramic main body and having respective one ends thereof exposed to the third and fourth side faces; external electrodes formed on the third and fourth side faces and electrically connected to the inner electrodes; and dielectric layers alternately stacked with the inner electrodes and made of ceramic powder, wherein a grain size of the ceramic powder is 130 μm or smaller. Acoustic noise generated from the multilayer ceramic capacitor can be reduced by adjusting the grain size of the ceramic powder, a chip permittivity, and the thickness of the dielectric layer, and thus, noise of an electronic product employing the multilayer ceramic capacitor can be reduced.
