摘要： A method of manufacturing a multilayer electronic component includes forming a stack by stacking a plurality of ceramic green sheets on which conductive patterns are disposed on a support film, cutting the stack in a second direction, perpendicular to a first direction which is a stacking direction of the plurality of ceramic green sheets, cutting the stack in a third direction, perpendicular to the first and second directions, to obtain a plurality of unit chips, separating the unit chip from the support film, arranging the unit chip such that one of side surfaces of the unit chip is in contact with an adhesive tape, and attaching another one of the side surfaces to a ceramic green sheet for a side margin portion, and forming a side margin portion on the another one of side surfaces.

摘要： A multilayer ceramic capacitor includes a ceramic body including an active portion that includes a dielectric layer and a plurality of internal electrodes overlapping other across the dielectric layer, and cover portions formed above and below the active portion, and including first and second surfaces opposing each other, third and fourth surfaces connecting the first and second surfaces, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other, and first and second side margin portions disposed on the first and second surfaces. In a cross-section of the ceramic body in a length-thickness (L-T) direction, a ratio Sd/Sc of an area Sd of a region except for the active portion to an overall area Sc of the section is greater than 27%.

摘要： A multilayer capacitor includes a body including a multilayer structure in which a plurality of dielectric layers are stacked, and further including a plurality of internal electrodes having a dielectric layer interposed therebetween and external electrodes disposed on external surfaces of the body and connected to the internal electrodes. The body further includes an active portion in which the plurality of internal electrodes are located to form capacitance and a side margin portion covering a first surface and a second surface of the active portion opposing each other. An average grain size of a dielectric layer included in the active portion is different from an average grain size of a dielectric layer included in the margin portion. The side margin portion includes an extending portion extending between the external electrodes and the internal electrodes to cover a portion of the internal electrodes.
