貼(tie)(tie)片電(dian)容(rong)(rong)(rong)(rong)是(shi)一種(zhong)(zhong)電(dian)容(rong)(rong)(rong)(rong)材質。貼(tie)(tie)片電(dian)容(rong)(rong)(rong)(rong)全稱(cheng)為：多層(ceng)（積層(ceng)，疊層(ceng)）片式(shi)陶瓷電(dian)容(rong)(rong)(rong)(rong)器（Multilayer Ceramic Capacitor， MLCC），也稱(cheng)為貼(tie)(tie)片電(dian)容(rong)(rong)(rong)(rong)，片容(rong)(rong)(rong)(rong)。貼(tie)(tie)片電(dian)容(rong)(rong)(rong)(rong)有兩種(zhong)(zhong)表示(shi)方法，一種(zhong)(zhong)是(shi)英寸單(dan)(dan)位來表示(shi)，一種(zhong)(zhong)是(shi)毫米單(dan)(dan)位來表示(shi)。
貼片電容的分類：
一(yi)(yi) 、NP0電容器：NP0是一(yi)(yi)種最常(chang)用的(de)具有溫度補償特性的(de)單片陶瓷電容器。它的(de)填充介質是由銣、釤和一(yi)(yi)些其它稀有氧化(hua)物組成的(de)。
二 、X7R電容器：X7R電容器被(bei)稱為溫度(du)穩定型(xing)的(de)陶瓷電容器。
三、 Z5U電(dian)容器(qi)：Z5U電(dian)容器(qi)稱為”通用”陶瓷單(dan)片電(dian)容器(qi)。
四、 Y5V電容(rong)(rong)器(qi)(qi)：Y5V電容(rong)(rong)器(qi)(qi)是一種有一定溫度(du)限(xian)制(zhi)的通用(yong)電容(rong)(rong)器(qi)(qi)，在-30℃到85℃范圍(wei)內其容(rong)(rong)量變化可達 22%到-82%。
區(qu)別：NP0、X7R、Z5U和Y5V的主要區(qu)別是它們(men)的填充介(jie)(jie)(jie)質不(bu)(bu)同(tong)。在相同(tong)的體(ti)積(ji)下(xia)由于填充介(jie)(jie)(jie)質不(bu)(bu)同(tong)所組成的電(dian)容(rong)器(qi)的容(rong)量就不(bu)(bu)同(tong)，隨之帶來的電(dian)容(rong)器(qi)的介(jie)(jie)(jie)質損耗、容(rong)量穩定性等也就不(bu)(bu)同(tong)。
