Multilayered ceramic capacitor

A multilayered ceramic capacitor, comprising:

• a capacitor body in which a plurality of dielectric layers having preset length and width are stacked;
• an internal electrode unit including a plurality of internal electrodes electrically independent from one another and arranged on each dielectric layer of the plurality of dielectric layers, the internal electrodes having an overlapping area between each of the plurality of internal electrodes on each of the dielectric layers and the internal electrodes of the adjacent dielectric layers forming a internal electrode group and the capacitance of each internal electrode group being 1uF or more;
• and
• an external electrode unit having a plurality of external electrodes horizontally arranged in the capacitor body and electrically connected to the internal electrodes;
• wherein the plurality of internal electrodes include protrusions connected to the external electrodes;
• and
• wherein the protrusions of the internal electrodes have a width larger than twice that of a distance from one side surface of the internal electrodes formed with the protrusions to the protrusions and less than four times thereof,
• wherein each dielectric layer of the plurality of dielectric layers is arranged with electrically independent first, second, third, and fourth internal electrodes disposed thereon,
• the internal electrode unit includes a first internal electrode group including the first internal electrodes of each dielectric layer, a second internal electrode group including the second internal electrodes of each dielectric layer, a third internal electrode group including the third internal electrodes of each dielectric layer, and a fourth internal electrode group including the fourth internal electrodes of each dielectric layer, and
• wherein an immediately adjacent distance between the first to fourth internal electrodes, each arranged on the plurality of dielectric layers is equal to or larger than half of an immediately adjacent distance between the first or the fourth internal electrode and a vertical side surface of the dielectric layer and is equal to or less than ⅔ of the immediately adjacent distance between the first or the fourth internal electrode and the vertical side surface of the dielectric layer.
