深(shen)圳市飛天鷹科技有(you)限(xian)公司是國家高(gao)新技術企業(ye)，有(you)著15年的(de)電(dian)源(yuan)(yuan)研發生產經(jing)驗，現有(you)超過200人的(de)研發團(tuan)隊，月產能在300萬(wan)只以上，是目(mu)前國內(nei)主要的(de)電(dian)源(yuan)(yuan)生產廠家之一，公司生產的(de)產品包(bao)括：小家電(dian)充(chong)(chong)電(dian)器、平衡(heng)車(che)充(chong)(chong)電(dian)器、電(dian)動(dong)車(che)充(chong)(chong)電(dian)器、礦機電(dian)源(yuan)(yuan)、USB充(chong)(chong)電(dian)器、QC3.0快(kuai)充(chong)(chong)充(chong)(chong)電(dian)器以及Type-c PD快(kuai)充(chong)(chong)充(chong)(chong)電(dian)器等(deng)，規格(ge)多(duo)種(zhong)，認證電(dian)源(yuan)(yuan)。

電(dian)容是開關電(dian)源(yuan)(yuan)中的(de)再普通不(bu)過的(de)器件，它(ta)可(ke)以用(yong)來降低(di)紋波噪聲，可(ke)以用(yong)來提(ti)高電(dian)源(yuan)(yuan)的(de)穩定(ding)性(xing)以及瞬(shun)態響應性(xing)，然而(er)，電(dian)容的(de)種類繁(fan)多，如何(he)通過技巧快(kuai)速進行選型，而(er)產(chan)品可(ke)靠性(xing)又高，性(xing)能又穩定(ding)呢？

首先我(wo)們來大致了解(jie)(jie)一下電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)種類。電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)種類較多，按封裝分有(you)貼片電(dian)(dian)(dian)(dian)容(rong)(rong)、插(cha)件電(dian)(dian)(dian)(dian)容(rong)(rong)，按介質分有(you)陶瓷電(dian)(dian)(dian)(dian)容(rong)(rong)，鉭(tan)電(dian)(dian)(dian)(dian)容(rong)(rong)，電(dian)(dian)(dian)(dian)解(jie)(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)、云母電(dian)(dian)(dian)(dian)容(rong)(rong)、薄膜電(dian)(dian)(dian)(dian)容(rong)(rong)等，按結構形勢(shi)分，有(you)固定(ding)電(dian)(dian)(dian)(dian)容(rong)(rong)、半固定(ding)電(dian)(dian)(dian)(dian)容(rong)(rong)、可變(bian)電(dian)(dian)(dian)(dian)容(rong)(rong)。在開關電(dian)(dian)(dian)(dian)源中(zhong)，我(wo)們使用最(zui)多的(de)就是陶瓷電(dian)(dian)(dian)(dian)容(rong)(rong)，電(dian)(dian)(dian)(dian)解(jie)(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)和鉭(tan)電(dian)(dian)(dian)(dian)容(rong)(rong)。其中(zhong)

1.陶瓷電容容值較小(xiao)(xiao)，高頻特性好(hao)，工作溫度范圍較廣，ESR較電解(jie)電容小(xiao)(xiao)，體積小(xiao)(xiao)，沒有極(ji)性；

2.電解電容(rong)容(rong)值可(ke)以(yi)做大，但工作溫度(du)范圍較(jiao)窄，ESR較(jiao)大，有極(ji)性；

3.鉭電(dian)容ESR最小，容值可比陶瓷電(dian)容大一些，有(you)極性，安規(gui)性能差(cha)，容易(yi)起火。

解了(le)以(yi)上三種電(dian)容的(de)特性，在使用它們的(de)時候(hou)就可以(yi)游刃(ren)有余(yu)了(le)。

另外電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)使(shi)用(yong)環(huan)境(jing)還分(fen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)內部(bu)(bu)環(huan)境(jing)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)外部(bu)(bu)環(huan)境(jing)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)內部(bu)(bu)環(huan)境(jing)包括頻(pin)率、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)(de)主要(yao)作(zuo)用(yong)等(deng)；根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)頻(pin)率可(ke)以(yi)(yi)(yi)確定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)種類；根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值可(ke)以(yi)(yi)(yi)確定(ding)選(xuan)型電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)耐壓(ya)值；在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)(de)主要(yao)作(zuo)用(yong)可(ke)以(yi)(yi)(yi)用(yong)來參(can)考選(xuan)型電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)容(rong)(rong)值等(deng)；根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)外部(bu)(bu)使(shi)用(yong)環(huan)境(jing)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)進(jin)行選(xuan)型，產品工作(zuo)的(de)(de)環(huan)境(jing)溫度，安規要(yao)求等(deng)，都可(ke)以(yi)(yi)(yi)用(yong)來縮小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)選(xuan)擇范(fan)圍。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)選(xuan)型不當，在應用(yong)中會出現爆(bao)漿、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液干涸等(deng)現象，最終導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)失效。
