摘要： The multilayer ceramic electronic component includes a ceramic body including a dielectric layer; and first and second internal electrodes disposed inside the ceramic body, and disposed to oppose each other with the dielectric layer interposed therebetween. When an average thickness of the dielectric layer is referred to as td and a standard deviation of a thickness of the dielectric layer in each position is referred to as σtd, while an average thickness of the first and second internal electrodes is referred to as to and a standard deviation of a thickness of a pre-determined region of any layer of the internal electrodes in each position is referred to as σte, a ratio (σte/σtd) of the standard deviation of the internal electrodes in each position to the standard deviation of the thickness of the dielectric layer in each position satisfies 1.10≤σte/σtd≤1.35.

摘要： A multilayer ceramic electronic component includes a ceramic body including first and second internal electrodes disposed to face each other and a dielectric layer interposed therebetween. When an average thickness of the dielectric layer is denoted as ‘td,’ an average thickness of the first and second internal electrodes is denoted as ‘te,’ and a standard deviation of thicknesses of an internal electrode, measured at a plurality of points in a predetermined region of the internal electrode, is denoted as ‘σte,’ a ratio of the standard deviation of thicknesses of the internal electrode to the average thickness of the dielectric layer, which is denoted as ‘σte/td,’ satisfies 0.12≤σte/td≤0.21.

摘要： A multilayer ceramic electronic component includes a ceramic body comprising dielectric layers and first and second internal electrodes disposed to face each other with respective dielectric layers interposed therebetween. The first internal electrode comprises a body portion contributing to the capacitance generation and a lead-out portion having a narrower width than the body portion and an end exposed from a surface, and the second internal electrode comprises a body portion contributing to the capacitance generation and a lead-out portion having a narrower width than the body portion and an end exposed from another surface. A ratio (w2/w1) of a width (w2) of the lead-out portion of the first and second internal electrodes to a width (w1) of the body portion satisfies 0.3≤w2/w1≤0.5.
