摘要： A multilayer electronic component includes a body including dielectric layers and internal electrodes alternately disposed in a first direction, and external electrodes disposed on the body to be connected to the internal electrodes. At least one internal electrode of the internal electrodes includes a plurality of disconnected portions penetrating through a respective internal electrode. A disconnected portion of the plurality of disconnected portions includes at least one of a pore or a dielectric substance disposed to connect adjacent dielectric layers to each other. A dielectric filling ratio, defined as a ratio of an overall length of the dielectric substance to an overall length of the disconnected portion on a cross section in the third and first directions, is more than 20% to 80% or less.

摘要： A multi-layered ceramic electronic component has a ceramic body including dielectric layers and a plurality of internal electrodes opposing each other with the dielectric layers interposed therebetween. External electrodes are disposed on an exterior of the ceramic body and are electrically connected to the internal electrodes. Each external electrode includes an electrode layer electrically connected to internal electrodes, and a conductive resin layer arranged on the electrode layer. The conductive resin layer extends to first and second surface of the ceramic body, and a ratio of a thickness (Tb) of the conductive resin layer extending onto the first surface and the second surface of the ceramic body to a length (Lm) of a length direction margin portion of the ceramic body satisfies 2 to 29%.

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.
