MLCCs come in a variety of dielectrics which are categorized into three classes which refer to their capacitance stability over temperature. Within each of these classes, each dielectric is designated using three characters such as C0G or U2J. Class 1 dielectrics are considered temperature compensating with very little change in capacitance versus temperature. The capacitance change for these dielectrics are measured in parts per million (ppm) per degree Celsius. Although the Class 1 MLCCs are very stable versus temperature, they have a very low permittivity and thus much lower capacitance compared to Class 2 and 3 dielectrics. Class 2 and 3 dielectrics are sensitive to temperature and will have a measurable capacitance change over the operating temperature range. The capacitance change for these dielectrics are measured in percent. Although Class 2 and 3 dielectrics are sensitive to temperature, they have a much higher permittivity compared to Class 1 capacitors and therefore can have much higher capacitance values in the same volume. For example, a Class 1 0805, 10V capacitor can have up to 47nF of capacitance. A Class 2 0805, 10V capacitor can have up to 10µF of capacitance which is over two hundred times that of the Class 1.
