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.
Analytical Drain Current and Capacitance Model for Amorphous InGaZnO TFTs Considering Temperature Characteristics
Analytical drain current and capacitance model is developed for the amorphous InGaZnO (a-IGZO) thin-film transistor (TFT). The numerical Pao-Sah model is presented to describe the temperature characteristics considering the deep and tail trap states in the energy gap of the a-IGZO thin film. The numerical model is successful for the TFT in both the …
