摘要:
A multilayer ceramic capacitor (100a) includes a body (110) including a capacitance region (115) in which a first internal electrode (121) and a second internal electrode (122) are alternately stacked in a first direction (T) with a dielectric layer (111) interposed therebetween and first and second external electrodes (131, 132) spaced apart from each other with the capacitance region (115) interposed therebetween and connected to the first and second internal electrodes (121, 122) respectively. The body (110) further includes cover layers (112) disposed on the capacitance region (115) in the first direction (T), a plurality of depressions or groove (141a, 142a, 141b, 142b) are disposed in an cover surface (112, 113) of the body (110) in the first direction (T), the depressions (141a, 142a, 141b, 142b) are spaced apart from outer end surfaces of the body (110) in the second direction (L), and a bending length of each external electrode (131, 132) in the second direction (L) is greater than a longest distance from each of the outer end surfaces of the body in the second direction (L) to a closer one of the depressions (141a, 141b, 142a, 142b). Therefore, the multilayer ceramic capacitor (100a) have an improved reliability by stably blocking the penetration of external moisture or foreign contaminant.
