1. Temperature-compensating-type multilayer ceramic capacitors (Class 1 in the official standards) This type uses a calcium zirconate-based dielectric material whose capacitance varies almost linearly with temperature. The slope to that temperature is called the temperature coefficient, and the value is expressed in 1/1,000,000 per 1°C (ppm/°C).
Calcium titanate for capacitors with a negative temperature coefficient. Class 2. This type of capacitor possesses high permittivity resulting in better volumetric efficiency than class 1 capacitors. It has lower accuracy and stability for smoothing, by-pass, coupling and decoupling applications It exhibits a non-linear temperature …

It refers to the capacitance variation over temperature for Class 2 ceramic capacitors for a Y5T dielectric. Here''s a table from Wikipedia on Ceramic Capacitors:. The +22/-33% rating tells you that the capacitor nominal value can change at the most +22% to -33% over the temperature range, that is the best you can infer from it.
EIA class II devices are those which retain a measure of dignity with regard to parameter stability over temperature (+/- 15% or better over a stated range, usually -50°C to 85°C or higher), while the EIA class III dielectrics abandon all pretense of temperature stability in pursuit of volumetric efficiency, having wider parameter variations ...
A capacitor''s temperature coefficient indicates how the temperature changes impact its capacitance value. Although the amount that the capacitance change is small, it is still a consideration for some applications. The coefficient is stated as parts per million per °C. Figure 3 illustrates the capacitance change curve against the temperature ...
Capacitor Characteristics and Capacitor Specifications
A. C0G and NP0 Class 1 ceramic temperature characteristics do not show significant changes in capacitance vs temperature. Generally, heat lowers Class 2 capacitors'' capacitances, however around the Curie point (approximately 120°C for BaTiO3), the capacitance increases.
