MULTI-LAYERED CERAMIC CAPACITOR AND BOARD FOR MOUNTING THE SAME

摘要

Provided is a laminated ceramic capacitor comprising: a ceramic body on which a plurality of dielectric layers are laminated; a first and a second body overlapped to each other, arranged in turns between the dielectric layers inside of the ceramic body; a plurality of first and second inner electrodes including a first and a second lid part extended to be exposed through one side of the ceramic body in the first and second bodies; and a first and a second outer electrode connected to the first and second lid parts on one side of the ceramic body. A conductive layer, Ni and Sn plating layers are laminated in the first and second outer electrodes. If an outer-most line exposed to one side of the ceramic body from at least one among the first and second lid parts is determined ′P′, the whole width of the conductive layer, Ni and Sn plating layers is determined ′a′ in a perpendicular direction of the conductive layer in ′P′, The thickness of the conductive layer is determined ′b′ in a perpendicular direction of the conductive layer in ′P′, the sum of the thicknesses of pores on the conductive layer in the perpendicular direction of the conductive layer in ′P′ is determined ′bp′, 0.264<=(b-bp)/a<=0.638 is satisfied.
