Abstract: A multilayer ceramic electronic component may include a ceramic body including dielectric layers and internal electrodes, electrode layers connected to the internal electrodes, and a conductive resin layer formed on the electrode layers and including a first conductor, a second conductor containing carbon nanotubes, and a base resin. When the multilayer ceramic electronic component is heat-tested by raising a temperature of the multilayer ceramic electronic component from room temperature to about 900° C. at a rate of about 10° C./min, a weight of the multilayer ceramic electronic component decreases by about 0.33% to about 2.19%.

Abstract: A multilayer ceramic capacitor includes a ceramic body having a dielectric layer, a plurality of internal electrodes disposed in the ceramic body, and a first side margin portion and a second side margin portion arranged on end portions of the internal electrodes exposed through respective opposing surfaces of the ceramic body. The ceramic body includes an active portion having the plurality of internal electrodes arranged to overlap each other with the dielectric layer interposed therebetween to form capacitance, and cover portions disposed above an uppermost and below a lowermost internal electrode of the active portion. The first and second side margin portions include tin (Sn), and a content of Sn included in the first and second side margin portions is greater than a content of Sn included in the dielectric layer of the active portion.
