一、鋁電解電容器是什么

鋁電解電容器是(shi)由鋁(lv)(lv)圓筒做(zuo)負(fu)極，里面(mian)裝有液體(ti)電(dian)(dian)解質，插入(ru)一片彎曲的(de)(de)(de)(de)鋁(lv)(lv)帶做(zuo)正極而制(zhi)成(cheng)的(de)(de)(de)(de)電(dian)(dian)容(rong)器(qi)(qi)稱作鋁(lv)(lv)電(dian)(dian)解電(dian)(dian)容(rong)器(qi)(qi)。它是(shi)一種(zhong)用(yong)鋁(lv)(lv)材料制(zhi)成(cheng)的(de)(de)(de)(de)電(dian)(dian)性能好(hao)、適用(yong)范圍寬、可(ke)靠性高(gao)的(de)(de)(de)(de)通用(yong)型(xing)電(dian)(dian)解電(dian)(dian)容(rong)器(qi)(qi)。

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)(ying)用(yong)領(ling)(ling)(ling)域(yu)的不同鋁電(dian)(dian)解(jie)電(dian)(dian)容(rong)器(qi)(qi)分為消(xiao)費(fei)類、工(gong)業(ye)類和(he)特種應(ying)(ying)用(yong)鋁電(dian)(dian)解(jie)電(dian)(dian)容(rong)器(qi)(qi)，消(xiao)費(fei)類鋁電(dian)(dian)解(jie)電(dian)(dian)容(rong)器(qi)(qi)主要(yao)用(yong)于(yu)節能照明、電(dian)(dian)視機(ji)、顯示器(qi)(qi)、計(ji)算機(ji)及空(kong)調等消(xiao)費(fei)類市(shi)場(chang)；工(gong)業(ye)類鋁電(dian)(dian)解(jie)電(dian)(dian)容(rong)器(qi)(qi)主要(yao)用(yong)于(yu)工(gong)業(ye)和(he)通訊(xun)電(dian)(dian)源(yuan)、專業(ye)變頻器(qi)(qi)、數(shu)控和(he)伺服系統、風(feng)力發電(dian)(dian)及汽車等工(gong)業(ye)領(ling)(ling)(ling)域(yu)；特種鋁電(dian)(dian)解(jie)電(dian)(dian)容(rong)器(qi)(qi)主要(yao)應(ying)(ying)用(yong)于(yu)軍事、航空(kong)航天(tian)以(yi)及其他特殊領(ling)(ling)(ling)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(ze)為導電性高分子。

由(you)于(yu)(yu)固(gu)態(tai)電(dian)(dian)(dian)(dian)容(rong)(rong)采用(yong)(yong)(yong)導(dao)電(dian)(dian)(dian)(dian)性高分(fen)子產品(pin)作(zuo)為介電(dian)(dian)(dian)(dian)材(cai)料，該(gai)材(cai)料不(bu)會與(yu)氧化鋁產生作(zuo)用(yong)(yong)(yong)，通電(dian)(dian)(dian)(dian)后不(bu)致(zhi)于(yu)(yu)發生爆炸的現象(xiang)；同時它為固(gu)態(tai)產品(pin)，自然也就不(bu)存在由(you)于(yu)(yu)受(shou)熱(re)膨脹導(dao)致(zhi)爆裂的情(qing)況(kuang)了。固(gu)態(tai)電(dian)(dian)(dian)(dian)容(rong)(rong)具備環保、低(di)阻抗、高低(di)溫穩(wen)定、耐高紋波及(ji)高信賴(lai)度等優越特性，是(shi)目前電(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)容(rong)(rong)產品(pin)中最高階的產品(pin)。由(you)于(yu)(yu)固(gu)態(tai)電(dian)(dian)(dian)(dian)容(rong)(rong)特性遠優于(yu)(yu)液態(tai)鋁電(dian)(dian)(dian)(dian)容(rong)(rong)，固(gu)態(tai)電(dian)(dian)(dian)(dian)容(rong)(rong)耐溫達(da)260度，且導(dao)電(dian)(dian)(dian)(dian)性、頻(pin)率特性及(ji)壽命均佳(jia)，適(shi)用(yong)(yong)(yong)于(yu)(yu)低(di)電(dian)(dian)(dian)(dian)壓、高電(dian)(dian)(dian)(dian)流(liu)的應用(yong)(yong)(yong)，主要應用(yong)(yong)(yong)于(yu)(yu)數(shu)字產品(pin)如薄型(xing)DVD、投影機及(ji)工業計算機等，近年(nian)來也被電(dian)(dian)(dian)(dian)腦板(ban)卡產品(pin)廣泛使用(yong)(yong)(yong)。
