下面是鋁電解電容器廠家對電容器的整合完整版:
鋁電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)器(qi)(qi)用浸有糊狀電(dian)(dian)(dian)解質的(de)(de)吸水紙(zhi)夾在兩(liang)條鋁箔(bo)中間卷繞而成,薄的(de)(de)化氧(yang)化膜(mo)(mo)作介質的(de)(de)電(dian)(dian)(dian)容(rong)器(qi)(qi)。因為(wei)氧(yang)化膜(mo)(mo)有單向導電(dian)(dian)(dian)性質,所以電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)器(qi)(qi)具有極性。容(rong)量大,能耐受大的(de)(de)脈動電(dian)(dian)(dian)流。容(rong)量誤差大,泄漏電(dian)(dian)(dian)流大;普(pu)通的(de)(de)不(bu)適于(yu)在高頻(pin)(pin)和低溫下應用,不(bu)宜使用在25kHz以上頻(pin)(pin)率。低頻(pin)(pin)旁路、信號耦合、電(dian)(dian)(dian)源(yuan)濾波(bo)。
鉭(tan)電解(jie)(jie)電容器用燒結的(de)鉭(tan)塊作正極,電解(jie)(jie)質使用固體二氧化錳。器、積分(fen)、振蕩電路(lu)紙介(jie)電容器
一般是(shi)用兩條鋁箔作為電極,中間以厚度(du)為0.008~0.012mm的電容(rong)器(qi)(qi)紙隔開重疊卷繞(rao)而成。 鋁電解電容(rong)器(qi)(qi)廠(chang)家制造工藝簡(jian)單,價格(ge)便宜(yi),能(neng)得到較大的電容(rong)量
金屬化(hua)聚丙烯(xi)電容器
一般在(zai)低頻電(dian)(dian)路(lu)內,通常不能(neng)在(zai)高(gao)(gao)于3~4MHz的頻率上(shang)運(yun)用。鋁電(dian)(dian)解電(dian)(dian)容(rong)(rong)器(qi)(qi)廠家電(dian)(dian)容(rong)(rong)器(qi)(qi)的耐(nai)壓比普通紙質電(dian)(dian)容(rong)(rong)器(qi)(qi)高(gao)(gao),穩定(ding)性也好,適用于高(gao)(gao)壓電(dian)(dian)路(lu)微調(diao)電(dian)(dian)容(rong)(rong)器(qi)(qi)(半可變電(dian)(dian)容(rong)(rong)器(qi)(qi)) 電(dian)(dian)容(rong)(rong)量可在(zai)某(mou)一小(xiao)范(fan)圍內調(diao)整,并(bing)可在(zai)調(diao)整后固定(ding)于某(mou)個電(dian)(dian)容(rong)(rong)值。
自愈式并聯電容(rong)器結構(gou)與紙質電容(rong)器相似,但用聚脂、聚苯(ben)乙烯等低損(sun)耗塑材作介質。頻率特性好,介電損(sun)耗小。不能做成(cheng)大的容(rong)量(liang),耐(nai)熱能力(li)差。
濾波(bo)器(qi)(qi)、積分(fen)、振蕩、定時電(dian)路。瓷(ci)介電(dian)容(rong)器(qi)(qi) 穿(chuan)心式(shi)或支柱(zhu)式(shi)結構瓷(ci)介電(dian)容(rong)器(qi)(qi),它的一(yi)個電(dian)極(ji)就(jiu)是安(an)裝螺(luo)絲。引線(xian)電(dian)感極(ji)小,頻率特(te)(te)性好,介電(dian)損(sun)耗小,有(you)溫度(du)補(bu)償作用(yong)。不能(neng)做(zuo)成大(da)的容(rong)量,受(shou)振動(dong)會(hui)引起容(rong)量變化。特(te)(te)別適于高(gao)頻旁路。獨石電(dian)容(rong)器(qi)(qi)(多層陶瓷(ci)電(dian)容(rong)器(qi)(qi))
瓷介微調電容器的Q值高,體積也小,通常可分為(wei)圓管(guan)式及(ji)圓片式兩種。
云母和聚(ju)苯乙烯介質的通常(chang)都采用彈簧式東,結構(gou)簡單,但穩定性較差。
線繞瓷(ci)介微(wei)調電(dian)容器是拆銅(tong)絲〈外電(dian)極(ji)〉來變(bian)動電(dian)容量的,故容量只能變(bian)小,不適合在(zai)需(xu)反復調試的場合使用(yong)。
用高介(jie)電(dian)常數的(de)電(dian)容(rong)器陶瓷(ci)〈鈦(tai)酸鋇(bei)一氧(yang)化鈦(tai)〉擠壓成圓管、圓片或圓盤(pan)作(zuo)為介(jie)質,并用燒滲(shen)法將銀(yin)鍍在陶瓷(ci)上作(zuo)為電(dian)極制成。它又分高頻瓷(ci)介(jie)和低(di)頻瓷(ci)介(jie)兩(liang)種。
具有小的正電容(rong)(rong)溫度系數的電容(rong)(rong)器,用(yong)于高(gao)穩定振蕩回路中(zhong),作為回路電容(rong)(rong)器及墊整電容(rong)(rong)器。
低(di)頻(pin)瓷介電容(rong)器(qi)限于在工作(zuo)頻(pin)率較低(di)的回路(lu)中作(zuo)旁路(lu)或隔直流用(yong),或對穩定性和損耗要求不高(gao)的場合〈包括高(gao)頻(pin)在內〉。這種電容(rong)器(qi)不宜使用(yong)在脈(mo)沖電路(lu)中,因為它們易(yi)于被脈(mo)沖電壓擊穿(chuan)。
