一、鋁電解電容器是什么

鋁電解電容器是由鋁(lv)圓筒(tong)做負極(ji)，里(li)面(mian)裝(zhuang)有液(ye)體電(dian)解(jie)質，插入(ru)一片彎曲的鋁(lv)帶做正(zheng)極(ji)而制成的電(dian)容器稱作鋁(lv)電(dian)解(jie)電(dian)容器。它是一種用(yong)鋁(lv)材料(liao)制成的電(dian)性(xing)能好、適用(yong)范圍寬、可靠性(xing)高的通用(yong)型電(dian)解(jie)電(dian)容器。

二、鋁電解電容器的用途

鋁電解電容器在電子線路中的基本作用一般概括為：通交流、阻直流，具有濾波、旁路、耦合和快速充放電的功能，并具有體積小、儲存電量大、性價比高的特性。隨著現代科技的進步與電容器性能的不斷提高，鋁電解電容器已廣泛應用于消費電子產品、通信產品、電腦及周邊產品、新能源、自動化控制、汽車工業、光電產品、高速鐵路與航空及軍事裝備等。

鋁電解電容器根據電解質形態的不同可劃分為液態鋁電解電容器和固態鋁電解電容器；按引出方式的不同可分為引線式、焊針式、焊片式、螺栓式、貼片式等五種。按應用領域的不同鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)分為(wei)消(xiao)費類、工業(ye)(ye)(ye)類和特種(zhong)(zhong)應用鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)，消(xiao)費類鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)主(zhu)要(yao)用于節能照明、電(dian)(dian)(dian)(dian)視機、顯示器(qi)(qi)、計算機及(ji)(ji)(ji)空調等消(xiao)費類市(shi)場(chang)；工業(ye)(ye)(ye)類鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)主(zhu)要(yao)用于工業(ye)(ye)(ye)和通訊電(dian)(dian)(dian)(dian)源(yuan)、專業(ye)(ye)(ye)變頻器(qi)(qi)、數控和伺服系統、風力發(fa)電(dian)(dian)(dian)(dian)及(ji)(ji)(ji)汽車等工業(ye)(ye)(ye)領域；特種(zhong)(zhong)鋁電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)主(zhu)要(yao)應用于軍事、航(hang)空航(hang)天以及(ji)(ji)(ji)其他(ta)特殊領域。

三、鋁電解電容與固態電容的區別

固態電容全稱為：固態鋁質電解電容。它與普通電容（即液態鋁質電解電容）最大差別在于采用了不同的介電材料，液態鋁電容介電材料為電解液，而固態電容的介電材(cai)料(liao)則為(wei)導電性高分(fen)子。
