    Abstract: A multilayer capacitor includes a body including a plurality of dielectric layers and a plurality of internal electrodes laminated in a first direction, and external electrodes. The body includes an active portion, in which the plurality of internal electrodes are disposed to form capacitance, corresponding to a region between internal electrodes disposed on an outermost side in the first direction, among the plurality of internal electrodes, a cover portion covering the active portion in the first direction, and a side margin portion covering the active portion in a second direction, perpendicular to the first direction, and 1.49

    Abstract: A multilayer capacitor includes a body including a laminate structure in which at least one first internal electrode and at least one second internal electrode are alternately stacked in a first direction with at least one dielectric layer therebetween, and first and second external electrodes spaced apart on the body, to be connected to at least one first internal electrode and at least one second internal electrode, respectively. The body includes, in a larger molar content, at least one selected from the group consisting of Dy, Tb, Y, Sm, Ho, Gd, Er, Ce, La and Nd in a capacitance formation region including a region between at least one first internal electrode and at least one second internal electrode than in a margin region including a region between a boundary line of at least one first internal electrode and at least one second internal electrode and a surface of the body.

    Abstract: A multilayer ceramic capacitor includes 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, exposed from the first and second surfaces, and having an end exposed from the third surface or the fourth surface, and a first side margin and a second side margin respectively disposed on the first and second surfaces, from which end portions of the plurality of internal electrodes are exposed. The first and second side margins include a base material powder of a barium titanate-based base powder and a subcomponent. The subcomponent includes terbium (Tb) as a first subcomponent including a lanthanide rare earth element, and a content ratio of the terbium (Tb) to a content of the first subcomponent (RE) excluding the terbium (Tb) satisfies 0.110≤Tb/RE≤2.333.
