陶瓷電(dian)容(rong)器的第二(er)個潛在(zai)(zai)缺陷是，它(ta)(ta)們具(ju)有相對較小的電(dian)容(rong)和低(di)ESR。在(zai)(zai)頻域(yu)和時域(yu)中(zhong)，這會帶來一些(xie)問題(ti)。如果它(ta)(ta)們被用作某個電(dian)源的輸入濾波電(dian)容(rong)器，則它(ta)(ta)們很容(rong)易隨輸入互(hu)連電(dian)感(gan)諧振(zhen)，形(xing)成一個我(wo)們在(zai)(zai)《電(dian)源設(she)計(ji)小貼士 3》和《電(dian)源設(she)計(ji)小貼士 4》contentId=53864 ）中(zhong)討(tao)論的振(zhen)蕩器。要想知道是否存(cun)(cun)在(zai)(zai)潛在(zai)(zai)問題(ti)，可將寄生互(hu)連電(dian)感(gan)估(gu)算為(wei)每英寸(cun) 15 nH，然后根據這兩篇(pian)文(wen)章介紹(shao)的方法把濾波輸出阻抗與電(dian)源輸入電(dian)阻進行(xing)對比(bi)。第二(er)個潛在(zai)(zai)問題(ti)存(cun)(cun)在(zai)(zai)于(yu)時域(yu)中(zhong)，介紹(shao)160度電(dian)容(rong)容(rong)量，我(wo)們可在(zai)(zai)以太網電(dian)源 （POE） 等系(xi)統中(zhong)看到它(ta)(ta)們的蹤影。

銀離(li)子(zi)(zi)遷移使電(dian)容(rong)器(qi)(qi)極(ji)(ji)間(jian)邊(bian)緣(yuan)電(dian)場發(fa)生(sheng)(sheng)嚴重(zhong)畸(ji)變，又因(yin)高濕度環境中陶瓷介質表(biao)面(mian)凝(ning)有水膜，使電(dian)容(rong)器(qi)(qi)邊(bian)緣(yuan)表(biao)面(mian)電(dian)暈(yun)放(fang)電(dian)電(dian)壓顯著(zhu)下降，工(gong)作(zuo)條(tiao)件下產生(sheng)(sheng)表(biao)面(mian)極(ji)(ji)間(jian)飛弧(hu)現象。嚴重(zhong)時導致電(dian)容(rong)器(qi)(qi)表(biao)面(mian)極(ji)(ji)間(jian)飛弧(hu)擊穿。表(biao)面(mian)擊穿與(yu)電(dian)容(rong)結(jie)構、極(ji)(ji)間(jian)距離(li)、負荷電(dian)壓、保護層的(de)疏水性與(yu)透(tou)濕性等因(yin)素(su)有關。邊(bian)緣(yuan)表(biao)面(mian)極(ji)(ji)間(jian)飛弧(hu)擊穿的(de)主(zhu)要原因(yin)是(shi)，介質留(liu)邊(bian)量較小，在潮濕環境中工(gong)作(zuo)時的(de)銀離(li)子(zi)(zi)遷移和表(biao)面(mian)水膜形成(cheng)使電(dian)容(rong)器(qi)(qi)邊(bian)緣(yuan)表(biao)面(mian)絕緣(yuan)由于銀離(li)子(zi)(zi)遷移的(de)產生(sheng)(sheng)與(yu)發(fa)展(zhan)需要一段時間(jian)，所以(yi)在耐壓試(shi)驗(yan)初期，失(shi)效模式(shi)以(yi)介質擊穿為主(zhu)，直(zhi)到試(shi)驗(yan)500h以(yi)后，只要失(shi)效模式(shi)才過(guo)度為邊(bian)緣(yuan)表(biao)面(mian)極(ji)(ji)間(jian)飛弧(hu)擊穿。
