       貼片鋁電解電容器(qi)(qi)是(shi)由鋁圓(yuan)筒做負極，里面裝(zhuang)有液體電解質，[敏感詞(ci)]一片彎曲的鋁帶做正極而(er)制成(cheng)(cheng)的電容(rong)器(qi)(qi)稱(cheng)作鋁電解電容(rong)器(qi)(qi)。它是(shi)一種用鋁材(cai)料制成(cheng)(cheng)的電性(xing)能好、適用范圍寬、可靠性(xing)高的通(tong)用型電解電容(rong)器(qi)(qi)。

       電(dian)(dian)容在(zai)電(dian)(dian)路(lu)中(zhong)實際要(yao)承受(shou)的電(dian)(dian)壓(ya)不(bu)(bu)能(neng)超過(guo)它(ta)的耐壓(ya)值。在(zai)濾波電(dian)(dian)路(lu)中(zhong)，電(dian)(dian)容的耐壓(ya)值不(bu)(bu)要(yao)小(xiao)于交流有效值的1.42倍。使(shi)用電(dian)(dian)解電(dian)(dian)容的時候，還要(yao)注(zhu)意正負極不(bu)(bu)要(yao)接(jie)反。

       不同電(dian)路應該選(xuan)用不同種類的電(dian)容(rong)。揩振(zhen)回路可(ke)(ke)以選(xuan)用云母(mu)、高頻陶瓷(ci)電(dian)容(rong)，隔(ge)直(zhi)流(liu)可(ke)(ke)以選(xuan)用紙介、滌(di)(di)綸、云母(mu)、電(dian)解(jie)、陶瓷(ci)等電(dian)容(rong)，濾波可(ke)(ke)以選(xuan)用電(dian)解(jie)電(dian)容(rong)，旁路可(ke)(ke)以選(xuan)用滌(di)(di)綸、紙介、陶瓷(ci)、電(dian)解(jie)等電(dian)容(rong)。

       電容(rong)(rong)在裝(zhuang)入電路(lu)(lu)前(qian)要(yao)檢查(cha)它(ta)(ta)有沒(mei)有短(duan)路(lu)(lu)、斷路(lu)(lu)和漏電等現(xian)象(xiang)，并且(qie)核對它(ta)(ta)的(de)(de)電容(rong)(rong)值。安(an)裝(zhuang)的(de)(de)時(shi)候，要(yao)使(shi)電容(rong)(rong)的(de)(de)類別、容(rong)(rong)量、耐壓等符號容(rong)(rong)易看到，以便核實。
