参数一：电容值

电容值C=Q/U。

要计算主板CPU供电部位对电容容量的需求，使用如下公式：

C = I/(∆V/∆t)

假如CPU的电流I为50A, ∆V=50mV时，∆t=10μS。则容量要求为C=10000μf。要得到理想的滤波效果的话，就要求要7颗1500μf的电容并联使用。

参数二：耐压值

耐压值是表示电容＋/－极之间的压差，如果出现过压现象，电容就会处于击穿状态，漏电流增大，电容内部发热巨增，电容内部的电解液会因高温变成气体致使电容内部压力增大。当这个压力超过电解电容的铝外壳承受压力的时候，电容就会发生。CPU的工作电压一般在1～2V之间，电容耐压能在4V以上就一般不会出问题，前提是电容极性不得插反！
