The Multilayer Ceramic Capacitors classification method :
Ceramic capacitors can be divided according to different packages and plug-Chip;
According to different media can be divided into two categories I and II class ceramic capacitors ceramic capacitors;
Usually NP0, SL0, C0G is I class ceramic capacitor, X7R, X5R, Y5U, Y5V ceramic capacitor is II class ceramic capacitor.

Class 2 ceramic capacitors Code system for some temperature ranges and inherent change of capacitance.
The first digit represents the low temperature, the second indicates a high temperature,and the third represents the deviation.
For example, a Z5U capacitor will operate from +10 °C to +85 °C with a capacitance change of at most +22% to −56%. 

Some commonly used class 2 ceramic capacitor materials are listed below:
* Y5V : Represents work in -30~+85℃, over the entire temperature range of deviation
-82%~+22%.
* X5R : Represents -55~+85℃, over the entire temperature range of ±15%.
* X7R : Represents work in -55~+125℃, over the full temperature range deviations of ±15%.
