的壽(shou)命(ming)就如(ru)同人的壽(shou)命(ming)一樣(yang)是(shi)無(wu)法預(yu)知(zhi)準確(que)的年限，但是(shi)很多大數據(ju)分析報告中有(you)平均壽(shou)命(ming)的概念(nian)。電(dian)源也(ye)一樣(yang)，影響其壽(shou)命(ming)的因數很多，所以(yi)(yi)一般電(dian)源的壽(shou)命(ming)都是(shi)以(yi)(yi)平均無(wu)故障時間(jian)來衡量的。

我們要(yao)減少故障發生的(de)可能(neng)(neng)性，來保證電(dian)(dian)源(yuan)(yuan)長期(qi)(qi)穩定的(de)工(gong)作。那就需要(yao)把控(kong)(kong)好電(dian)(dian)源(yuan)(yuan)生命(ming)周期(qi)(qi)中的(de)兩個(ge)重要(yao)環節：電(dian)(dian)源(yuan)(yuan)的(de)研(yan)發、電(dian)(dian)源(yuan)(yuan)的(de)生產(chan)(chan)。電(dian)(dian)源(yuan)(yuan)研(yan)發需要(yao)保證電(dian)(dian)源(yuan)(yuan)的(de)性能(neng)(neng)滿足我們的(de)規格(ge)書要(yao)求，保證在電(dian)(dian)源(yuan)(yuan)正常生命(ming)周期(qi)(qi)中的(de)電(dian)(dian)源(yuan)(yuan)性能(neng)(neng)指(zhi)標。電(dian)(dian)源(yuan)(yuan)模(mo)塊類(lei)產(chan)(chan)品對生產(chan)(chan)流(liu)程及(ji)工(gong)藝管控(kong)(kong)要(yao)求很高(gao)，需要(yao)高(gao)品質的(de)生產(chan)(chan)設備及(ji)管理，才能(neng)(neng)達(da)到預期(qi)(qi)的(de)產(chan)(chan)品品質。

電源(yuan)適配(pei)器(qi)(qi)壽(shou)(shou)命(ming)(ming)與使用元器(qi)(qi)件之(zhi)間(jian)也滿足木桶效(xiao)應(ying)，所有器(qi)(qi)件壽(shou)(shou)命(ming)(ming)都達到(dao)規定壽(shou)(shou)命(ming)(ming)才能保(bao)證電源(yuan)的最終使用壽(shou)(shou)命(ming)(ming)。一般關鍵器(qi)(qi)件受到(dao)的電應(ying)力大(da)，發熱量高，機器(qi)(qi)內(nei)部(bu)溫(wen)(wen)度(du)上升快，溫(wen)(wen)度(du)對器(qi)(qi)件壽(shou)(shou)命(ming)(ming)影響較大(da)，所以對器(qi)(qi)件的壽(shou)(shou)命(ming)(ming)最終評估尤為重(zhong)要。想要電源(yuan)適配(pei)器(qi)(qi)安全長(chang)壽(shou)(shou)命(ming)(ming)，首先要控制好元器(qi)(qi)件的質量。
