Abstract: A multilayer ceramic electronic component includes a body with a plurality of first and second internal electrodes alternately arranged with dielectric layers interposed therebetween. There may be M each of third and fourth external electrodes on opposing sides of the body, where M is greater than or equal to 3 and all external electrodes have different polarities than the adjacent external electrodes. There may be N via electrodes penetrating through the body, where N is greater than or equal to 3 and the via electrodes are connected to either of the first or second internal electrodes. The multilayer ceramic electronic component may achieve low equivalent series inductance (ESL) characteristics and may reduce the mounting area on the circuit board.
