Nomenclature of patch capacitance.
At present, the relatively large amount of monolithic ceramic capacitors (commonly known as patch capacitors). The chip capacitors produced by AVX Company are NPO, X7R, Z5U, Y5V and so on. Different companies may have different naming methods for capacitors with different functions. Here we quote the naming method of AVX Company. .

The main difference between the above capacitor types is that their filling media are different. In the same volume, the capacity of the capacitor is different when the filling medium is different, so the dielectric loss and capacity stability of the capacitor are also different. Therefore, when using the capacitor, the corresponding capacitor should be selected according to the effect of the capacitor in the circuit.

貼片電容的命名

目前用量比較大的單片陶瓷電容器(通稱貼片電容)。AVX公司出產(chǎn)的貼片電容型號(hào)有NPO、X7R、Z5U、Y5V等。不一樣的公司對(duì)于功能不一樣的電容器可能有不一樣的命名辦法，這兒咱們引證的是AVX公司的命名辦法。  
  上述電容器型號(hào)的區(qū)別主要是它們的填充介質(zhì)不一樣。在相同體積下填充介質(zhì)不一樣所構(gòu)成的電容器的容量就不一樣，因此電容器的介質(zhì)損耗、容量穩(wěn)定性等也就不一樣。所以在使用電容器時(shí)應(yīng)根據(jù)需要電容器在電路中效果來選用相應(yīng)的電容器。
