電(dian)解電(dian)容(rong)(rong)器(qi)普遍應用于(yu)(yu)各種電(dian)路中(zhong)。由于(yu)(yu)電(dian)容(rong)(rong)器(qi)的絕緣層(ceng)來(lai)(lai)自金屬(shu)電(dian)極的非(fei)常(chang)薄的氧化膜，這種電(dian)容(rong)(rong)器(qi)的容(rong)(rong)量可以(yi)做得(de)非(fei)常(chang)大，從幾微法到幾法拉不等。在(zai)電(dian)路中(zhong)，用于(yu)(yu)精度低但容(rong)(rong)量大的儲能濾(lv)波電(dian)路。由于(yu)(yu)其(qi)體積(ji)相對較大，往往采用鋁筒封裝，所以(yi)在(zai)電(dian)路板上通常(chang)會鶴(he)立雞群。而(er)兩者的本質(zhi)(zhi)區(qu)別在(zai)于(yu)(yu)介(jie)電(dian)材(cai)料(liao)的不同。液(ye)體電(dian)解電(dian)容(rong)(rong)器(qi)的電(dian)介(jie)質(zhi)(zhi)材(cai)料(liao)是(shi)(shi)電(dian)解質(zhi)(zhi)，而(er)固(gu)體電(dian)容(rong)(rong)器(qi)是(shi)(shi)導電(dian)聚合物。兩者的區(qu)別直(zhi)接導致了(le)固(gu)態(tai)電(dian)容(rong)(rong)比較大的優勢，不容(rong)(rong)易發生危險。電(dian)容(rong)(rong)做為電(dian)氣、電(dian)子元(yuan)器(qi)件對于(yu)(yu)我們這些(xie)電(dian)工人(ren)來(lai)(lai)講是(shi)(shi)非(fei)常(chang)熟(shu)悉的。

MLCC已成為應用較普遍的(de)(de)電(dian)(dian)容(rong)器，對一個國家電(dian)(dian)子信息產業的(de)(de)制造水平有著重大影響(xiang)。MLCC的(de)(de)結構主要包括三部(bu)(bu)分(fen)：陶瓷介(jie)(jie)質、內電(dian)(dian)極(ji)(ji)(ji)和外電(dian)(dian)極(ji)(ji)(ji)。因(yin)此，在(zai)制造MLCC的(de)(de)過(guo)程(cheng)中(zhong)，我(wo)們可(ke)以選擇不同(tong)材料的(de)(de)電(dian)(dian)介(jie)(jie)質和極(ji)(ji)(ji)板(ban)，以及連接極(ji)(ji)(ji)板(ban)的(de)(de)引(yin)線。即(ji)內部(bu)(bu)電(dian)(dian)極(ji)(ji)(ji)、外部(bu)(bu)電(dian)(dian)極(ji)(ji)(ji)、端(duan)子和介(jie)(jie)電(dian)(dian)材料。由于其內部(bu)(bu)結構，MLCC在(zai)英語(yu)聽(ting)力和英語(yu)聽(ting)力方面具(ju)有獨(du)特(te)的(de)(de)優(you)勢。因(yin)此，陶瓷電(dian)(dian)容(rong)器具(ju)有更好的(de)(de)高頻特(te)性(xing)。MLCC電(dian)(dian)容(rong)特(te)性(xing)：機械(xie)強度(du)(du)：硬而脆(cui)，這是陶瓷材料的(de)(de)機械(xie)強度(du)(du)特(te)性(xing)。熱脆(cui)性(xing)：MLCC的(de)(de)內應力非(fei)常復雜，因(yin)此它對溫(wen)度(du)(du)沖擊(ji)的(de)(de)抵抗力非(fei)常有限。電(dian)(dian)解電(dian)(dian)容(rong)被普遍應用在(zai)各類電(dian)(dian)路中(zhong)。淮安射頻電(dian)(dian)容(rong)多少(shao)錢
