MLCC已成為應用(yong)較普遍的(de)(de)電(dian)容(rong)器(qi)，對一個國家(jia)電(dian)子信息(xi)產業的(de)(de)制造(zao)水(shui)平有(you)著重大影響。MLCC的(de)(de)結構主要包括三部分：陶(tao)瓷介質(zhi)、內電(dian)極(ji)(ji)(ji)和外電(dian)極(ji)(ji)(ji)。因此，在(zai)(zai)制造(zao)MLCC的(de)(de)過程中，我(wo)們可以(yi)(yi)選擇(ze)不同(tong)材料(liao)的(de)(de)電(dian)介質(zhi)和極(ji)(ji)(ji)板，以(yi)(yi)及(ji)連接極(ji)(ji)(ji)板的(de)(de)引線。即內部電(dian)極(ji)(ji)(ji)、外部電(dian)極(ji)(ji)(ji)、端子和介電(dian)材料(liao)。由(you)于其(qi)內部結構，MLCC在(zai)(zai)英(ying)語(yu)聽力(li)(li)和英(ying)語(yu)聽力(li)(li)方面具有(you)獨特(te)(te)的(de)(de)優勢。因此，陶(tao)瓷電(dian)容(rong)器(qi)具有(you)更(geng)好的(de)(de)高頻特(te)(te)性。MLCC電(dian)容(rong)特(te)(te)性：機械(xie)強度：硬而脆(cui)，這是陶(tao)瓷材料(liao)的(de)(de)機械(xie)強度特(te)(te)性。熱脆(cui)性：MLCC的(de)(de)內應力(li)(li)非常(chang)(chang)復(fu)雜，因此它對溫度沖擊的(de)(de)抵抗力(li)(li)非常(chang)(chang)有(you)限。電(dian)容(rong)器(qi)的(de)(de)電(dian)容(rong)量的(de)(de)基本單位是法拉(F)。在(zai)(zai)電(dian)路圖中通常(chang)(chang)用(yong)字母C表(biao)示電(dian)容(rong)元件。上海貼(tie)片鋁電(dian)解電(dian)容(rong)規(gui)格
