    Abstract: A multilayer electronic component includes a body including a dielectric layer and internal electrodes, and including first and second surfaces, third and fourth surfaces, fifth and sixth surfaces, external electrodes disposed on the third and fourth surfaces, and side margin portions disposed on the fifth and sixth surfaces. The side margin portions include a first region adjacent to the internal electrodes and a second region adjacent to outside of the side margin portions. In a Raman spectra obtained by analyzing one point located in the first and second region respectively, peak X appears in a Raman shift of 450 cm−1 to 600 cm−1. When a minimum value of the Raman shift at which the peak X appears in the Raman spectra of the first region is λ(cm−1), a minimum value of the Raman shift at which the peak X appears in the Raman spectra of the second region is λ+0.75 cm−1 or greater.

    Abstract: A multilayer ceramic electronic component includes: a ceramic body including a dielectric layer and first and second internal electrodes stacked to be alternately exposed to one side surface and the other side surface with the dielectric layer disposed therebetween; and first and second external electrodes disposed on an external surface of the ceramic body to be connected to the first and second internal electrodes, respectively, in which the ceramic body includes an area of overlap in a thickness direction of the first and second internal electrodes, margin region, and/or cover region, and the margin region in the width direction and/or the cover region includes a phosphoric acid-based second phase.

    Abstract: 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%.
