三星电机工规超高容MLCC (1206 inch, 220uF, X6S, 4V)

▷ AI服务器的功率消耗是普通服务器的5倍，使用的MLCC也比普通服务器多12.5倍。[Figure1, 2] 应用于AI服务器的MLCC需要高容量、高电压、小型化来应对高功率，这种需求在持续增加。

▷ AI服务器采用的CPU, GPU, TPU等高性能IC，同时进行高运算操作时，会瞬间发生大 的电流变化。超高容MLCC将最大程度减少电压下降，快速补偿电流波动，来提高电源稳定性。一般容量的MLCC高频响应虽然出色，但容量较低时，在低频段储能能力不足。相反超高容MLCC在低频段也能充分储存能量，在宽带宽上表现出稳定的性能。

 

▷ 另外，通过在AI服务器上使用超高容MLCC， 在Set安装方面可以减少零部件数量， 简化PCB设计，提高安装面积的空间利用率。例如，如Figure3所示，1个SP-CAP(330uF) 的面积可以使用4个MLCC(180uF x 4@1Vdc)，可节省约35%的空间，电容量可提高218%。而且阻抗特性也比SP-CAP提高了90%。[Figure3]
