片式多層陶瓷電容器是由印好電極（內電極）的陶瓷介質膜片以錯位的方式疊合起來，經過一次性高溫燒結形成陶瓷芯片，再在芯片的兩端封上金屬層（外電極），從而形成一個類似獨石的結構體，故也叫獨石電容器。
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.
購買商品的一般決策邏輯是：能不能用？好不好用？耐不耐用？價格優不優惠？其實這個邏輯也可以套用到片式多層陶瓷電容的選型過程中：
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要滿足電路要求
Firstly, the parameters of chip multilayer ceramic capacitors should meet the circuit requirements
其次就是參數與介質是否能讓系統工作在最佳狀態
The second is whether the parameters and media can make the system work in the best state
再次，片式多層陶瓷電容是否存在不良品，可靠性如何
Thirdly, is there any defective product in the chip multilayer ceramic capacitor and how reliable is it
最后，價格是否有優勢，供應商配合是否及時。
Finally, whether the price is advantageous and whether the supplier cooperates in time.

不同介質性能決定了片式多層陶瓷電容不同的應用
Different dielectric properties determine the different applications of chip multilayer ceramic capacitors
（1）C0G電容器具有高溫度補償特性，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電容器是溫度穩定型陶瓷電容器，適合要求不高的工業應用
X7R capacitor is a temperature stable ceramic capacitor, which is suitable for industrial applications with low requirements
（3）Z5U電容器特點是小尺寸和低成本，尤其適合應用于去耦電路
Z5u capacitor features small size and low cost, especially suitable for decoupling circuit
（4）Y5V電容器溫度特性最差，但容量大，可取代低容鋁電解電容
Y5V capacitor has the worst temperature characteristic, but it has large capacity and can replace low capacity aluminum electrolytic capacitor
片式多層陶瓷電容常見的有C0G(NP0)、X7R、Z5U、Y9V等不一樣的物質規格型號，不一樣的規格型號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的關鍵差別是他們的添充物質不一樣。在相同體積下，由填充介質構成的電容器的容量不同，與之相伴的電容器的介電損耗、容量穩定性等也不同，因此在使用電容器的情況下，根據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.
