Embodiment

[0100] Table 1 below shows the change in equivalent series resistance (ESR) according to the change in the aspect ratio (L / D) of the second conductor in the conductive resin layer of the multilayer ceramic capacitor.

[0103] From Table 1 above, it can be understood that when L / D is less than 1, ESR is 70Ω or more; however, when L / D is 1 or more, ESR is 50Ω or less, which is significantly reduced.

[0104] In addition, when L / D is 2 or more, ESR is also greatly reduced. Therefore, when L / D is 2 or more, an ESR of 20 mΩ or less is obtained.

[0105] As described above, according to exemplary embodiments of the present disclosure, there are provided a multilayer ceramic capacitor having a reduced equivalent series resistance (ESR) when absorbing external shocks and preventing penetration of plating solution, and a method of manufacturing the same, and A board for mounting mul...
