    Abstract: A multilayer ceramic capacitor includes: a ceramic body having first and second surfaces opposing each other and third and fourth surfaces connecting the first and second surfaces to each other; a plurality of internal electrodes disposed in the ceramic body, exposed to the first and second surfaces, and each having one end exposed to the third or fourth surface; and first and second side margin portions disposed on the first and second surfaces and covering exposed surfaces of the internal electrodes. A dielectric composition contained in the first and second side margin portions is different from a dielectric composition contained in the ceramic body, the first and second side margin portions contain a barium titanate-based base material powder and magnesium (Mg), manganese (Mn), and aluminum (Al) as accessory ingredients, and a content ratio of manganese (Mn) to magnesium (Mg), manganese (Mn), and aluminum (Al) satisfies 0.316≤Mn/(Mn+Mg+Al)≤0.500, based on a molar content of Mn, Mg and Al in the first and second side margin portions.

    Abstract: A multilayer ceramic electronic component includes: a capacitor body including a plurality of dielectric layers and a plurality of internal electrodes; with external electrodes disposed on the capacitor body and electrically connected to the internal electrodes, wherein the capacitor body includes an active region in which internal electrodes having different polarities from each other overlap each other to form capacitance, and a margin part defined as region except for the active region. A concentration of an additive element in the margin part is higher than the concentration of the additive element in the active region, and the margin part has a concentration gradient of the additive element from a surface of the capacitor body toward the active region.

    Abstract translation: 多层陶瓷电子部件包括：电容器主体，包括多个电介质层和多个内部电极; 外部电极设置在电容器本体上并与内部电极电连接，其中电容器主体包括有源区，其中彼此具有不同极性的内部电极彼此重叠以形成电容，并且将边界部分定义为除 活跃区域。 边缘部分中的添加元素的浓度高于有源区域中的添加元素的浓度，并且边缘部分具有从电容器体的表面向有源区域的添加元素的浓度梯度。
