摘要： A multilayer capacitor and a board having the same provide high capacitance and low equivalent series inductance (ESL). The multilayer capacitor includes a capacitor body including an active region, including first and second internal electrodes, and first and second cover regions. Third and fourth internal electrodes are alternately disposed in the cover region adjacent to a mounting surface. First and second external electrodes respectively contact the first and second internal electrodes to provide capacitance. First and second via electrodes are disposed in the cover region, where the first via electrode connects the third internal electrode and a first band portion of the first external electrode to each other, and where the second via electrode connects the fourth internal electrode and a second band portion of the second external electrode to each other.

摘要： A multilayer ceramic electronic component includes: a ceramic body and first and second external electrodes on external surfaces of the ceramic body. The ceramic body includes first and second internal electrodes facing each other with dielectric layers interposed therebetween. The ceramic body includes an active portion in which capacitance is formed and cover portions on upper and lower surfaces of the active portion, respectively. The ratio of the thickness of the first and second external electrodes to the thickness of the cover portion is proportional to the inverse of the cube root of the ratio of the Young's Modulus of each of the first and second external electrodes to the Young's modulus of the cover portion.
