    IPC: H01G4/12

    Abstract: A multilayer ceramic electronic component includes: a body part including dielectric layers and internal electrodes disposed to face each other with respective dielectric layers interposed therebetween; and external electrodes disposed on an outer surface of the body part and electrically connected to the internal electrodes. The dielectric layer includes grains including: a semiconductive or conductive grain core region containing a base material represented by ABO3, where A is at least one of Ba, Sr, and Ca, and B is at least one of Ti, Zr, and Hf, and a doping material including a rare earth element; and an insulating grain shell region enclosing the grain core region.

    Abstract: A multilayer ceramic capacitor includes a ceramic body including a dielectric layer and including first and second surfaces opposing each other, third and fourth surfaces connecting the first and second surfaces. A plurality of internal electrodes is disposed inside the ceramic body, connected to the first and second surfaces, and have one ends connected to the third and fourth surfaces. First and second side margin parts are disposed on end portions of the internal electrodes connected to the first and second surfaces. The ceramic body includes an active portion forming capacitance by including the plurality of internal electrodes disposed to oppose each other with the dielectric layer interposed therebetween. An average Sn content in a region adjacent to the side margin part of the active portion is greater than an average Sn content in a central region of the active portion.
