  • Patent number: 11133131
    Abstract: 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.
