  • Patent number: 11742144
    Abstract: A multilayer ceramic electronic component includes a ceramic body including a dielectric layer including a grain and first and second internal electrodes stacked in a third direction with the dielectric layer interposed therebetween, and including a first surface and a second surface opposing each other in a third direction, a third surface and a fourth surface opposing each other in a second direction, and a fifth surface and a sixth surface opposing each other in a first direction; and first and second external electrodes disposed on the fifth surface and the sixth surface of the ceramic body, respectively, and a ratio, G/I, of a particle size, G, of a grain of the dielectric layer to a thickness, I, of each of the first and second internal electrodes is 0.3 or more and 0.5 or less.

  • Patent number: 11393631
    Abstract: An electronic component includes a capacitor body having first to sixth surfaces, the capacitor body including a plurality of dielectric layers stacked in a first direction connecting the fifth and sixth surfaces and first and second internal electrodes alternately disposed with the dielectric layer interposed therebetween; first and second external electrodes disposed on the first surface of the capacitor body, to be spaced apart from each other in a second direction connecting the third and fourth surfaces; and first and second metal frames connected to the first and second external electrodes, respectively. The first internal electrode includes a first lead portion exposed through the first surface of the capacitor body and connected to the first external electrode. The second internal electrode includes a second lead portion exposed through the first surface of the capacitor body and connected to the second external electrode.

  • Patent number: 11049661
    Abstract: A multilayer electronic component includes a body including a dielectric layer and first and second internal electrodes, and including first to sixth surfaces, a first external electrode including a first electrode layer extending to a portion of each of the first, second, fifth, and sixth surfaces and a first conductive resin layer, and a second external electrode including a second electrode layer extending to a portion of each of the first, second, fifth, and sixth surfaces and a second conductive resin layer. R1 and R2 satisfy R1>R2, in which R1 is defined as a surface roughness of each of the first, second, fifth, and sixth surfaces in contact with the first and second electrode layers, and R2 is defined as a surface roughness of each of the first, second, fifth, and sixth surfaces in contact with the first and second conductive resin layers.
