片式多層陶瓷電容器是由印好電極（內(nèi)電極）的陶瓷介質(zhì)膜片以錯(cuò)位的方式疊合起來(lái)，經(jīng)過(guò)一次性高溫?zé)Y(jié)形成陶瓷芯片，再在芯片的兩端封上金屬層（外電極），從而形成一個(gè)類似獨(dú)石的結(jié)構(gòu)體，故也叫獨(dú)石電容器。
Chip multilayer ceramic capacitor is composed of ceramic dielectric membrane with printed electrodes (inner electrode) stacked in a staggered way. After one-time high-temperature sintering, a ceramic chip is formed, and then a metal layer (outer electrode) is sealed at both ends of the chip to form a structure similar to a monolith, so it is also called monolith capacitor.
那么片式多層陶瓷電容器如何選型？選型要素根據(jù)什么一起跟隨小編一起了解下吧。
How to select the type of chip multilayer ceramic capacitor? According to what selection elements, follow the editor to understand it.
購(gòu)買商品的一般決策邏輯是：能不能用？好不好用？耐不耐用？?jī)r(jià)格優(yōu)不優(yōu)惠？其實(shí)這個(gè)邏輯也可以套用到片式多層陶瓷電容的選型過(guò)程中：
The general decision logic of purchasing goods is: can it be used? Is it easy to use? Is it durable? Is the price good or not? In fact, this logic can also be applied to the selection process of chip multilayer ceramic capacitors
首先片式多層陶瓷電容參數(shù)要滿足電路要求

不同介質(zhì)性能決定了片式多層陶瓷電容不同的應(yīng)用
Different dielectric properties determine the different applications of chip multilayer ceramic capacitors
（1）C0G電容器具有高溫度補(bǔ)償特性，適合作旁路電容和耦合電容
C0g capacitor has high temperature compensation characteristic, which is suitable for bypass capacitor and coupling capacitor
（2）X7R電容器是溫度穩(wěn)定型陶瓷電容器，適合要求不高的工業(yè)應(yīng)用
X7R capacitor is a temperature stable ceramic capacitor, which is suitable for industrial applications with low requirements
?。?）Z5U電容器特點(diǎn)是小尺寸和低成本，尤其適合應(yīng)用于去耦電路

片式多層陶瓷電容常見的有C0G(NP0)、X7R、Z5U、Y9V等不一樣的物質(zhì)規(guī)格型號(hào)，不一樣的規(guī)格型號(hào)有不一樣的特性和主要用途。
Chip multilayer ceramic capacitors often have different material specifications such as c0g (np0), X7R, z5u, y9v, etc. different specifications and models have different characteristics and main uses.
C0G、X7R、Z5U和Y9V的關(guān)鍵差別是他們的添充物質(zhì)不一樣。在相同體積下，由填充介質(zhì)構(gòu)成的電容器的容量不同，與之相伴的電容器的介電損耗、容量穩(wěn)定性等也不同，因此在使用電容器的情況下，根據(jù)電容器在電路中的作用而選擇不同的電容器。
The key difference between c0g, X7R, z5u and y9v is that they have different filling materials. In the same volume, the capacity of the capacitor composed of filling medium is different, and the dielectric loss and capacity stability of the capacitor are also different. Therefore, in the case of using the capacitor, different capacitors should be selected according to the function of the capacitor in the circuit.
