首先要明確(que)一點(dian)，鋁電(dian)解電(dian)容(rong)一定會壞，只是時間問(wen)題。影響(xiang)(xiang)電(dian)容(rong)壽命(ming)的(de)(de)原(yuan)因有很多(duo)，過(guo)電(dian)壓(ya)，逆電(dian)壓(ya)，高溫(wen)，急(ji)速充(chong)放電(dian)等等，正常(chang)(chang)使用的(de)(de)情況(kuang)下，最大的(de)(de)影響(xiang)(xiang)就是溫(wen)度(du)，因為(wei)溫(wen)度(du)越高電(dian)解液的(de)(de)揮發損耗越快。需要注(zhu)意的(de)(de)是這里(li)的(de)(de)溫(wen)度(du)不是指(zhi)環境或，是指(zhi)鋁箔(bo)工作溫(wen)度(du)。廠(chang)商通常(chang)(chang)會將電(dian)容(rong)壽命(ming)和測試(shi)溫(wen)度(du)標注(zhu)在(zai)電(dian)容(rong)本體。

因電(dian)(dian)(dian)容的(de)(de)(de)工(gong)作溫(wen)度(du)每增高(gao)(gao)10℃壽(shou)(shou)命(ming)減半(ban)，所以不要(yao)以為2000小時(shi)壽(shou)(shou)命(ming)的(de)(de)(de)鋁電(dian)(dian)(dian)解電(dian)(dian)(dian)容就(jiu)比1000小時(shi)的(de)(de)(de)好，要(yao)注意確(que)認壽(shou)(shou)命(ming)的(de)(de)(de)測試溫(wen)度(du)。每個廠商(shang)都有溫(wen)度(du)和壽(shou)(shou)命(ming)的(de)(de)(de)計(ji)算公式，在(zai)設(she)計(ji)電(dian)(dian)(dian)容時(shi)要(yao)參(can)照實(shi)際(ji)數據進行計(ji)算。需要(yao)了(le)解的(de)(de)(de)是要(yao)提(ti)高(gao)(gao)鋁電(dian)(dian)(dian)解電(dian)(dian)(dian)容的(de)(de)(de)壽(shou)(shou)命(ming)，第一(yi)要(yao)降低工(gong)作溫(wen)度(du)，在(zai)PCB上遠離熱源(yuan)，第二考慮使用(yong)最高(gao)(gao)工(gong)作溫(wen)度(du)高(gao)(gao)的(de)(de)(de)電(dian)(dian)(dian)容，當然(ran)價(jia)格也會(hui)高(gao)(gao)一(yi)些(xie)。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中實際要(yao)(yao)承受的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不能超過它的(de)(de)耐(nai)壓(ya)值(zhi)。在濾(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)耐(nai)壓(ya)值(zhi)不要(yao)(yao)小于交(jiao)流(liu)有(you)效值(zhi)的(de)(de)1.42倍。使用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)時候，還要(yao)(yao)注意正負極不要(yao)(yao)接反。不同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)應該選用(yong)不同種類(lei)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)。揩振回路(lu)(lu)(lu)可以選用(yong)云母、高頻陶(tao)瓷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，隔直流(liu)可以選用(yong)紙(zhi)介、滌綸(lun)、云母、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)、陶(tao)瓷等電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，濾(lv)波可以選用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，旁路(lu)(lu)(lu)可以選用(yong)滌綸(lun)、紙(zhi)介、陶(tao)瓷、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)等電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)在裝入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)(lu)前要(yao)(yao)檢(jian)查它有(you)沒(mei)有(you)短路(lu)(lu)(lu)、斷(duan)路(lu)(lu)(lu)和(he)漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)等現(xian)象(xiang)，并且核對(dui)它的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)值(zhi)。安裝的(de)(de)時候，要(yao)(yao)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)類(lei)別、容(rong)(rong)(rong)量、耐(nai)壓(ya)等符(fu)號容(rong)(rong)(rong)易看到，以便核實。
