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(an)應(ying)(ying)用(yong)領域的不(bu)同鋁(lv)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)器分為(wei)消費類、工業類和(he)(he)特(te)種(zhong)應(ying)(ying)用(yong)鋁(lv)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)器，消費類鋁(lv)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)器主要(yao)用(yong)于(yu)(yu)節(jie)能照(zhao)明、電(dian)(dian)(dian)(dian)(dian)視(shi)機、顯示(shi)器、計算(suan)機及(ji)空(kong)(kong)調等(deng)(deng)消費類市場；工業類鋁(lv)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)器主要(yao)用(yong)于(yu)(yu)工業和(he)(he)通訊電(dian)(dian)(dian)(dian)(dian)源、專業變(bian)頻器、數控和(he)(he)伺服系統、風(feng)力(li)發電(dian)(dian)(dian)(dian)(dian)及(ji)汽車等(deng)(deng)工業領域；特(te)種(zhong)鋁(lv)電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容(rong)器主要(yao)應(ying)(ying)用(yong)于(yu)(yu)軍(jun)事、航(hang)空(kong)(kong)航(hang)天以及(ji)其(qi)他特(te)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(jie)電(dian)材料則為導電(dian)性高分子。

由(you)于(yu)固態電(dian)(dian)容采(cai)用(yong)(yong)導電(dian)(dian)性(xing)(xing)(xing)高(gao)(gao)(gao)分子產(chan)品作為介電(dian)(dian)材(cai)料(liao)，該材(cai)料(liao)不(bu)會與氧化鋁產(chan)生(sheng)作用(yong)(yong)，通電(dian)(dian)后不(bu)致(zhi)于(yu)發生(sheng)爆炸的(de)現象；同時(shi)它為固態產(chan)品，自然也(ye)就不(bu)存在由(you)于(yu)受熱膨脹導致(zhi)爆裂的(de)情況了。固態電(dian)(dian)容具備環保、低阻抗、高(gao)(gao)(gao)低溫(wen)穩定(ding)、耐高(gao)(gao)(gao)紋波及(ji)(ji)高(gao)(gao)(gao)信(xin)賴度等優越特(te)性(xing)(xing)(xing)，是目前電(dian)(dian)解(jie)電(dian)(dian)容產(chan)品中最高(gao)(gao)(gao)階的(de)產(chan)品。由(you)于(yu)固態電(dian)(dian)容特(te)性(xing)(xing)(xing)遠優于(yu)液態鋁電(dian)(dian)容，固態電(dian)(dian)容耐溫(wen)達260度，且導電(dian)(dian)性(xing)(xing)(xing)、頻率特(te)性(xing)(xing)(xing)及(ji)(ji)壽命均佳，適用(yong)(yong)于(yu)低電(dian)(dian)壓、高(gao)(gao)(gao)電(dian)(dian)流(liu)的(de)應用(yong)(yong)，主要應用(yong)(yong)于(yu)數(shu)字(zi)產(chan)品如薄型DVD、投影機及(ji)(ji)工(gong)業計算(suan)機等，近(jin)年來也(ye)被電(dian)(dian)腦板卡(ka)產(chan)品廣泛(fan)使用(yong)(yong)。
