Multilayer ceramic capacitor and board with the same mounted thereon |
摘要 |
A multilayer ceramic capacitor may include: a ceramic body including a plurality of dielectric layers; a capacitor unit disposed in an upper portion of the ceramic body and including a plurality of first and second internal electrodes; an equivalent series resistance (ESR) controller disposed in a lower portion of the ceramic body and including a plurality of third and fourth internal electrodes; a gap layer disposed between the capacitor unit and the ESR controller; first and second external electrodes disposed on the first and second end surfaces of the ceramic body and electrically connected to the first and second internal electrodes; and third and fourth external electrodes disposed on the first and second lateral surfaces of the ceramic body and electrically connected to the third and fourth internal electrodes. |

1. A multilayer ceramic capacitor, comprising:
a ceramic body including a plurality of dielectric layers, first and second main surfaces opposing one another in a thickness direction, first and second end surfaces opposing one another in a length direction, and first and second lateral surfaces opposing one another in a width direction; a capacitor unit disposed in an upper portion of the ceramic body and including a plurality of first and second internal electrodes, which are disposed with the respective dielectric layers interposed between the first and second internal electrodes while being alternately exposed to the first and second end surfaces of the ceramic body; an equivalent series resistance (ESR) controller disposed in a lower portion of the ceramic body and including a plurality of third and fourth internal electrodes, which are disposed with the dielectric layers interposed between the third and fourth electrodes while being alternately exposed to the first and second lateral surfaces of the ceramic body; a gap layer disposed between the capacitor unit and the ESR controller; first and second external electrodes disposed on the first and second end surfaces of the ceramic body and electrically connected to the first and second internal electrodes; and third and fourth external electrodes disposed on the first and second lateral surfaces of the ceramic body and electrically connected to the third and fourth internal electrodes, wherein when a distance from the mounting surface of the ceramic body to a lower end of the ESR controller is defined as A and a distance from the mounting surface of the ceramic body to a lower end of the capacitor unit is defined as B, 2.959≦B/A ≦18.576 is satisfied. |
