鉭(tan)電(dian)容(rong)(rong)(rong)的(de)(de)性能(neng)優良(liang)，是一(yi)種體(ti)積(ji)小(xiao)、電(dian)容(rong)(rong)(rong)大的(de)(de)產(chan)(chan)品。在電(dian)源濾波(bo)器(qi)(qi)(qi)、交流旁路(lu)和其他應用(yong)中，幾乎沒(mei)有競爭對手。鉭(tan)電(dian)解電(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)主要用(yong)于(yu)濾波(bo)、儲能(neng)和轉換、標記旁路(lu)、耦(ou)合和去耦(ou)，以(yi)(yi)及作為(wei)時(shi)間常(chang)數元件等(deng)。因為(wei)它(ta)們可(ke)以(yi)(yi)儲電(dian)，可(ke)以(yi)(yi)充(chong)放(fang)電(dian)。在應用(yong)中，應注意其性能(neng)特點。正確使(shi)用(yong)有助于(yu)充(chong)分發揮其功能(neng)，如(ru)考慮產(chan)(chan)品的(de)(de)工作環境和加熱溫度，采(cai)取降(jiang)額使(shi)用(yong)等(deng)措施，使(shi)用(yong)不(bu)(bu)(bu)(bu)當(dang)(dang)會(hui)影響產(chan)(chan)品的(de)(de)使(shi)用(yong)壽命。比如(ru)3354USB接口輸出，降(jiang)額后耐(nai)壓(ya)達(da)到5V，集成(cheng)度比較高。當(dang)(dang)陶(tao)瓷(ci)電(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)不(bu)(bu)(bu)(bu)能(neng)滿足高耐(nai)壓(ya)和大容(rong)(rong)(rong)量的(de)(de)要求時(shi)，我們不(bu)(bu)(bu)(bu)得(de)不(bu)(bu)(bu)(bu)選(xuan)擇(ze)鉭(tan)電(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)。陶(tao)瓷(ci)的(de)(de)儲能(neng)效(xiao)果(guo)并不(bu)(bu)(bu)(bu)能(neng)按照并聯的(de)(de)電(dian)容(rong)(rong)(rong)來等(deng)效(xiao)，達(da)到同樣效(xiao)果(guo)的(de)(de)成(cheng)本(ben)也很高。MLCC（Multi-layer Ceramic Capacitors）是片式多層陶(tao)瓷(ci)電(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)英文(wen)縮寫。常(chang)州陶(tao)瓷(ci)電(dian)解電(dian)容(rong)(rong)(rong)品牌

當(dang)電(dian)(dian)容(rong)器的內部連(lian)接(jie)性(xing)能(neng)惡化或(huo)失效(xiao)時，通常會(hui)(hui)出(chu)現開路。電(dian)(dian)氣連(lian)接(jie)的惡化可(ke)能(neng)是由腐蝕(shi)、振動(dong)或(huo)機械應力引起的。鋁(lv)電(dian)(dian)解(jie)電(dian)(dian)容(rong)器在(zai)(zai)高(gao)溫或(huo)濕熱環境(jing)下工作時，陽極(ji)(ji)(ji)引出(chu)箔(bo)可(ke)能(neng)因電(dian)(dian)化學腐蝕(shi)而(er)斷(duan)裂。陽極(ji)(ji)(ji)引出(chu)箔(bo)與陽極(ji)(ji)(ji)箔(bo)接(jie)觸不良也(ye)會(hui)(hui)造成電(dian)(dian)容(rong)器間歇性(xing)開路。1)在(zai)(zai)工作初期，鋁(lv)電(dian)(dian)解(jie)電(dian)(dian)容(rong)器的電(dian)(dian)解(jie)液在(zai)(zai)負載工作過程中會(hui)(hui)不斷(duan)修復(fu)和增(zeng)(zeng)厚陽極(ji)(ji)(ji)氧(yang)化膜(稱為填(tian)形(xing)效(xiao)應)，導(dao)(dao)致(zhi)電(dian)(dian)容(rong)下降(jiang)。2)在(zai)(zai)使用后期，由于電(dian)(dian)解(jie)液損耗(hao)大(da)，溶液變稠，電(dian)(dian)阻率增(zeng)(zeng)大(da)，增(zeng)(zeng)加了等(deng)效(xiao)串聯電(dian)(dian)阻和電(dian)(dian)解(jie)液損耗(hao)。同時，隨著溶液粘度(du)的增(zeng)(zeng)加，鋁(lv)箔(bo)表面不均勻的氧(yang)化膜難以充(chong)分接(jie)觸，減(jian)少了電(dian)(dian)解(jie)電(dian)(dian)容(rong)器的有效(xiao)極(ji)(ji)(ji)板面積，導(dao)(dao)致(zhi)電(dian)(dian)容(rong)量(liang)下降(jiang)。此外，在(zai)(zai)低溫下工作時，電(dian)(dian)解(jie)液的粘度(du)也(ye)會(hui)(hui)增(zeng)(zeng)加，導(dao)(dao)致(zhi)電(dian)(dian)解(jie)電(dian)(dian)容(rong)損耗(hao)增(zeng)(zeng)加，電(dian)(dian)容(rong)下降(jiang)。徐(xu)州(zhou)貼片鋁(lv)電(dian)(dian)解(jie)電(dian)(dian)容(rong)價格MLCC的結構主要包括三大(da)部分：陶瓷介質，內電(dian)(dian)極(ji)(ji)(ji)，外電(dian)(dian)極(ji)(ji)(ji)。

無論(lun)是筆(bi)記(ji)本(ben)電(dian)(dian)腦還是手(shou)機，對電(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)要(yao)求越來越高，通常(chang)(chang)在(zai)電(dian)(dian)源(yuan)(yuan)(yuan)網絡上并聯大量的(de)(de)MLCC電(dian)(dian)容(rong)，如(ru)BUCK、BOOST架構的(de)(de)電(dian)(dian)源(yuan)(yuan)(yuan)，當設計(ji)異(yi)常(chang)(chang)或者負載工(gong)作模式異(yi)常(chang)(chang)時，就很(hen)(hen)容(rong)易(yi)產生“嘯叫”。在(zai)筆(bi)記(ji)本(ben)電(dian)(dian)腦中(zhong)(zhong)，當電(dian)(dian)腦處于休(xiu)眠(mian)狀態，或者啟動(dong)攝像(xiang)頭時，容(rong)易(yi)產生嘯叫。在(zai)手(shou)機中(zhong)(zhong)，較典型(xing)的(de)(de)一個案(an)例是GSM所(suo)用(yong)的(de)(de)PA電(dian)(dian)源(yuan)(yuan)(yuan)，此(ci)電(dian)(dian)源(yuan)(yuan)(yuan)線(xian)上的(de)(de)特點是功率波動(dong)大、波動(dong)頻率為典型(xing)的(de)(de)217Hz，落入人(ren)耳聽(ting)覺(jue)范圍內(20Hz~20Khz)，當GSM通話時，用(yong)于聽(ting)診器聽(ting)此(ci)電(dian)(dian)源(yuan)(yuan)(yuan)線(xian)上的(de)(de)電(dian)(dian)容(rong)，很(hen)(hen)容(rong)易(yi)聽(ting)到“滋(zi)(zi)滋(zi)(zi)”嘯叫音。
