A multilayer ceramic capacitor include: a ceramic body including first and second surfaces opposing each other and third and fourth surfaces connecting the first and second surfaces; a plurality of internal electrodes disposed inside the ceramic body and exposed to the first and second surfaces, the plurality internal electrodes each having one end exposed to the third or fourth surface; and first and second side margin portions disposed on sides of the internal electrodes exposed to the first and second surfaces. A dielectric composition of the first and second side margin portions is different from a dielectric composition of the ceramic body, and a dielectric constant of the first and second side margin portions is lower than a dielectric constant of the ceramic body.

Multilayer ceramic capacitor

A multilayer ceramic electronic component includes a ceramic body in which dielectric layers and internal electrodes are alternately disposed. Ceramic-metal compound layers are disposed on interfaces between the internal electrodes and the dielectric layers. Additionally, in some examples, spaces between adjacent internal electrodes are fully occupied by the dielectric layers and the dielectric layers contain a ceramic-metal compound containing metal particle. The ceramic-metal compound layer may have an embossing type configuration or a dendrite type configuration.

The ceramic dielectric composition may have high room-temperature permittivity and excellent ESD protection characteristics and may secure withstand voltage characteristics while implementing relatively high capacitance.

A dielectric ceramic composition contains a base material main ingredient and an accessory ingredient. The base material main ingredient includes a first base material main ingredient containing BaTiOand a second base material main ingredient containing (NaK)NbO. The base material main ingredient is represented by (1&#x2212;x)BaTiO-x(NaK)NbO, in which x and y satisfy 0.005&#x2266;x&#x2266;0.5 and 0.3&#x2266;y&#x2266;1.0, respectively.

A dielectric ceramic composition may include: a base powder represented by BaTiOand accessory components. In an XRD measurement of a dielectric material in which the base powder and the accessory components are sintered, when a (1, 1, 0) plane peak of a BaTiOcrystal phase is converted into 1.00, a secondary phase peak of pyrochlore (RETiO) (RE is a rare earth element) at about 30.5 degrees, as compared with the (1, 1, 0) plane peak, is 0.01 or less.
