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(ying)用(yong)(yong)(yong)領(ling)域的不同(tong)鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)分為消(xiao)費類(lei)(lei)、工(gong)(gong)業(ye)類(lei)(lei)和特(te)種應(ying)用(yong)(yong)(yong)鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)，消(xiao)費類(lei)(lei)鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)主要(yao)用(yong)(yong)(yong)于(yu)節能(neng)照明、電(dian)(dian)(dian)(dian)視機(ji)(ji)、顯示(shi)器(qi)、計算(suan)機(ji)(ji)及空調等(deng)消(xiao)費類(lei)(lei)市場；工(gong)(gong)業(ye)類(lei)(lei)鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)主要(yao)用(yong)(yong)(yong)于(yu)工(gong)(gong)業(ye)和通訊電(dian)(dian)(dian)(dian)源、專業(ye)變頻器(qi)、數(shu)控(kong)和伺(si)服(fu)系統、風力發電(dian)(dian)(dian)(dian)及汽車等(deng)工(gong)(gong)業(ye)領(ling)域；特(te)種鋁電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)主要(yao)應(ying)用(yong)(yong)(yong)于(yu)軍(jun)事(shi)、航(hang)空航(hang)天以及其(qi)他特(te)殊領(ling)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(dian)材料則為(wei)導(dao)電(dian)性高分子(zi)。

由(you)于(yu)固(gu)態(tai)電(dian)(dian)(dian)容(rong)(rong)采用(yong)(yong)導電(dian)(dian)(dian)性高分(fen)子產(chan)(chan)品(pin)(pin)作為介電(dian)(dian)(dian)材料(liao)，該(gai)材料(liao)不(bu)(bu)會與氧化(hua)鋁產(chan)(chan)生作用(yong)(yong)，通電(dian)(dian)(dian)后不(bu)(bu)致于(yu)發生爆(bao)炸的現(xian)象；同(tong)時它為固(gu)態(tai)產(chan)(chan)品(pin)(pin)，自然(ran)也(ye)就不(bu)(bu)存在由(you)于(yu)受熱(re)膨脹導致爆(bao)裂的情況了。固(gu)態(tai)電(dian)(dian)(dian)容(rong)(rong)具備環保、低(di)阻抗、高低(di)溫(wen)穩定(ding)、耐高紋波(bo)及(ji)(ji)高信賴度(du)等優(you)越特(te)性，是目前電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)(rong)產(chan)(chan)品(pin)(pin)中最高階的產(chan)(chan)品(pin)(pin)。由(you)于(yu)固(gu)態(tai)電(dian)(dian)(dian)容(rong)(rong)特(te)性遠優(you)于(yu)液態(tai)鋁電(dian)(dian)(dian)容(rong)(rong)，固(gu)態(tai)電(dian)(dian)(dian)容(rong)(rong)耐溫(wen)達260度(du)，且(qie)導電(dian)(dian)(dian)性、頻率特(te)性及(ji)(ji)壽命(ming)均(jun)佳，適用(yong)(yong)于(yu)低(di)電(dian)(dian)(dian)壓、高電(dian)(dian)(dian)流(liu)的應(ying)用(yong)(yong)，主(zhu)要應(ying)用(yong)(yong)于(yu)數字(zi)產(chan)(chan)品(pin)(pin)如薄(bo)型DVD、投影機及(ji)(ji)工業(ye)計算(suan)機等，近年來也(ye)被電(dian)(dian)(dian)腦板卡產(chan)(chan)品(pin)(pin)廣泛(fan)使(shi)用(yong)(yong)。
