4.4.4 Temperature coefficient of capacitance. Throughout the temperature range specified the capacitance shall not change by more
than .04 %/°C relative to the capacitance value measured at TA = 25°C. The temperature coefficient of capacitance may be computed by
the following formula:

TCC =
CT (+85°C) - CT (-65°C)
