我的分析：电容通常提供的参数主要是耐压与电容值，在规定的耐压范围内，使用电容，一般都不会击穿。在交流电路中，电容的容抗 Zc= 1/ωC, ω为角频率（ω = 2πf），如f = 50Hz，则ω=314。如电容二端施加一电压U，则电容的电流 Ic=U*ωC。施加最大耐压Um 时的电容电流，就是该电容容许的最大流过的电流。如果施加的电压超过规定的耐压值，虽然电容的电流可以增大，但电容极易被击穿。下面分几个问题进行分析： 1、电容的电压 Uc=I /ωC，如流过1微法电容的电流为70mA=0.07A，电流频率f=50Hz，则：电容的电压Uc=0.07÷（314×0.000001）= 223 V，如果70mA是1μF电容的最大容许电流，则该电容的耐压=223V，即可以将1μF电容直接接在220V交流电源上，不过此时是该电容工作在其耐压的上限值区，若长时间工作不太可靠的，一般选择电容的耐压参数应大于工作电压的2～3倍。 AS-B838-032 Digital Output Module Modicon
