鉭電(dian)(dian)容(rong)的性能優良，是一種體積小、電(dian)(dian)容(rong)大的產(chan)(chan)品。在電(dian)(dian)源濾(lv)波(bo)器、交流旁路(lu)和(he)(he)其(qi)他應用(yong)(yong)中(zhong)，幾(ji)(ji)乎沒有競爭對手。鉭電(dian)(dian)解(jie)電(dian)(dian)容(rong)器主(zhu)要(yao)用(yong)(yong)于(yu)濾(lv)波(bo)、儲(chu)能和(he)(he)轉換(huan)、標(biao)記旁路(lu)、耦合(he)和(he)(he)去耦，以及作(zuo)(zuo)為(wei)時間常數(shu)(shu)元件等。因為(wei)它們可以儲(chu)電(dian)(dian)，可以充放電(dian)(dian)。在應用(yong)(yong)中(zhong)，應注(zhu)意(yi)其(qi)性能特(te)點。正確(que)使用(yong)(yong)有助(zhu)于(yu)充分發揮其(qi)功能，如考慮(lv)產(chan)(chan)品的工作(zuo)(zuo)環境(jing)和(he)(he)加熱(re)溫度，采取降(jiang)額使用(yong)(yong)等措施(shi)，使用(yong)(yong)不(bu)(bu)當會影響產(chan)(chan)品的使用(yong)(yong)壽命。比(bi)如3354USB接口(kou)輸出，降(jiang)額后耐壓達到(dao)5V，集成度比(bi)較高(gao)。當陶瓷電(dian)(dian)容(rong)器不(bu)(bu)能滿(man)足高(gao)耐壓和(he)(he)大容(rong)量(liang)的要(yao)求(qiu)時，我(wo)們不(bu)(bu)得不(bu)(bu)選擇(ze)鉭電(dian)(dian)容(rong)器。陶瓷的儲(chu)能效(xiao)果并不(bu)(bu)能按照并聯(lian)的電(dian)(dian)容(rong)來(lai)等效(xiao)，達到(dao)同樣效(xiao)果的成本(ben)也很高(gao)。電(dian)(dian)解(jie)電(dian)(dian)容(rong)器多數(shu)(shu)采用(yong)(yong)卷繞結(jie)構，很容(rong)易(yi)擴大體積，因此(ci)單位(wei)體積電(dian)(dian)容(rong)量(liang)非常大，比(bi)其(qi)它電(dian)(dian)容(rong)大幾(ji)(ji)倍到(dao)幾(ji)(ji)十倍。北京(jing)電(dian)(dian)容(rong)貼片規格
