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)用領域(yu)的不同鋁(lv)(lv)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容器分為消費(fei)類(lei)、工(gong)業類(lei)和(he)特種(zhong)應(ying)用鋁(lv)(lv)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容器，消費(fei)類(lei)鋁(lv)(lv)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容器主要用于節能照明(ming)、電(dian)(dian)(dian)(dian)(dian)視機、顯示(shi)器、計算(suan)機及(ji)空調等(deng)消費(fei)類(lei)市(shi)場；工(gong)業類(lei)鋁(lv)(lv)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容器主要用于工(gong)業和(he)通訊(xun)電(dian)(dian)(dian)(dian)(dian)源(yuan)、專業變頻器、數(shu)控和(he)伺(si)服系統、風力發電(dian)(dian)(dian)(dian)(dian)及(ji)汽車等(deng)工(gong)業領域(yu)；特種(zhong)鋁(lv)(lv)電(dian)(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)(dian)容器主要應(ying)用于軍事、航(hang)空航(hang)天以及(ji)其他(ta)特殊領域(yu)。

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料則為(wei)導電性高分子(zi)。

由于固(gu)態(tai)電(dian)(dian)容(rong)采用(yong)(yong)導(dao)電(dian)(dian)性(xing)(xing)高(gao)分子(zi)產(chan)品(pin)(pin)(pin)作為(wei)(wei)介電(dian)(dian)材(cai)料，該材(cai)料不(bu)會與氧化鋁產(chan)生作用(yong)(yong)，通電(dian)(dian)后(hou)不(bu)致(zhi)于發生爆炸的(de)現象；同時它為(wei)(wei)固(gu)態(tai)產(chan)品(pin)(pin)(pin)，自然(ran)也就不(bu)存在由于受(shou)熱膨脹導(dao)致(zhi)爆裂(lie)的(de)情況了。固(gu)態(tai)電(dian)(dian)容(rong)具備環保(bao)、低阻抗(kang)、高(gao)低溫(wen)穩定、耐高(gao)紋波及高(gao)信賴(lai)度等優越特性(xing)(xing)，是目前電(dian)(dian)解電(dian)(dian)容(rong)產(chan)品(pin)(pin)(pin)中最(zui)高(gao)階的(de)產(chan)品(pin)(pin)(pin)。由于固(gu)態(tai)電(dian)(dian)容(rong)特性(xing)(xing)遠優于液態(tai)鋁電(dian)(dian)容(rong)，固(gu)態(tai)電(dian)(dian)容(rong)耐溫(wen)達260度，且導(dao)電(dian)(dian)性(xing)(xing)、頻率特性(xing)(xing)及壽(shou)命均佳，適用(yong)(yong)于低電(dian)(dian)壓、高(gao)電(dian)(dian)流的(de)應用(yong)(yong)，主要(yao)應用(yong)(yong)于數字產(chan)品(pin)(pin)(pin)如薄型DVD、投影機及工業計算機等，近年來也被電(dian)(dian)腦(nao)板卡(ka)產(chan)品(pin)(pin)(pin)廣泛使(shi)用(yong)(yong)。
