Abstract
A multilayer ceramic electronic component includes a ceramic body having a plurality of dielectric layers and a plurality of internal electrodes disposed with the dielectric layers interposed therebetween. An external electrode is disposed on the outside of the ceramic body. A coating layer is formed on at least a portion of an outer surface of the ceramic body and includes a water-repellent coating agent and at least one of a heat stabilizer that removes free radicals generated from the water-repellent coating agent, and an antioxidant that decomposes a free radical forming factor. The coating layer improves moisture resistance reliability and durability of the component during thermal and environmental stress.
