MULTI-LAYERED CERAMIC CAPACITOR AND BOARD FOR MOUNTING THE SAME

摘要

The present invention includes: a ceramic body which includes a dielectric layer and has first and second principal sides (S1, S2) facing mutually, first and second lateral sides (S5, S6) facing mutually, and first and second cross sections (S3, S4) facing mutually; active layers which are arranged to face mutually by putting the dielectric layer in the center and forms a capacity by including multiple first and second internal electrodes which are alternatively exposed to the first lateral side (S5) and the second lateral side (S6); upper and lower cover layers which are formed in the upper and lower parts of the active layer; and a second external electrode which is formed on the first lateral side (S5) of the ceramic body, is formed on the second lateral side (S6) with a first external electrode electrically connected to the first internal electrode, and is electrically connected to the second internal electrode. The provided multilayer ceramic capacitor satisfies 0.75W <= T <= 1.25W when the thickness of the ceramic body is T and the width of the ceramic body is W, satisfies 30μm <= G <= 0.9W when an interval between the first external electrode and the second external electrode is G, and satisfies that the average number of dielectric grains per layer is two or more in the vertical direction of the dielectric layer.
