層出不窮(qiong)的(de)手持(chi)設備(bei)，以輕為美(mei)，以薄為俏，手機(ji)、照相、MP3、收音機(ji)等功能還一(yi)個也不能少(shao)，對元器件(jian)廠(chang)商的(de)要(yao)求也順勢提高。盡管核心處理器一(yi)直是大家關注(zhu)的(de)重點，身為配角(jiao)的(de)電(dian)容(rong)器、電(dian)阻器等無源器件(jian)在(zai)推進產品的(de)小(xiao)型化方(fang)面也扮(ban)演著重要(yao)的(de)角(jiao)色。

獨石電(dian)容(rong)器是片(pian)式(shi)(shi)多層陶(tao)瓷電(dian)容(rong)器的另(ling)一個(ge)稱呼，縮寫是MLCC，是世界上用(yong)量最(zui)(zui)大、發展最(zui)(zui)快的片(pian)式(shi)(shi)元(yuan)件品種。獨石電(dian)容(rong)具有體積小，容(rong)量大，絕(jue)緣(yuan)電(dian)阻(zu)高等特點，可在(zai)高頻、高溫環境下(xia)使用(yong)，因此(ci)特別適合(he)手持設備(bei)。

獨石電容器的(de)發(fa)展趨(qu)勢(shi)是：片式(shi)化率迅速增(zeng)長；尺寸不(bu)(bu)(bu)斷(duan)縮小；厚度不(bu)(bu)(bu)斷(duan)變(bian)薄(bo)變(bian)輕；生產規模不(bu)(bu)(bu)斷(duan)擴(kuo)大；復合(he)度不(bu)(bu)(bu)斷(duan)提高(gao)；技術(shu)不(bu)(bu)(bu)斷(duan)更新(xin)。低失(shi)真率和沖擊噪聲(sheng)小、壽命長、高(gao)安全性和高(gao)可(ke)靠性、低成(cheng)本的(de)獨石電容器不(bu)(bu)(bu)斷(duan)涌(yong)現。

目前，主要(yao)的(de)(de)獨石(shi)電(dian)容器(qi)(qi)的(de)(de)國外生產廠家(jia)有村田制(zhi)作(zuo)所(MURATA)、TDK、AVX、京瓷、太(tai)陽誘(you)電(dian)、三(san)星(xing)電(dian)子等，國內的(de)(de)風(feng)華高科也是(shi)獨石(shi)電(dian)容器(qi)(qi)的(de)(de)重要(yao)廠商。
