Generally the temperature coefficient is expressed in the units of parts per million per degree centigrade (PPM/0C) or as a percent change with a particular range of temperatures. Some capacitors are linear (class 1 capacitors), these are highly stable with temperatures; such capacitors have a zero temperature coefficient.
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). The temperature coefficient of capacitance is defined by Equation 1 from the capacitance value C 25 at the reference temperature *1 and the capacitance value C T at the category upper temperature *2.
Generally the capacitance value which is printed on the body of a capacitor is measured with the reference of temperature 250C and also the TC of a capacitor which is mentioned in the datasheet must be considered for the applications which are operated below or above this temperature.
Temperature Coefficient of Capacitance (TCC) describes the maximum change in capacitance over a specified temperature range. The capacitance value stated by the manufacturer is established at a reference temperature of 25°C. TCC should always be considered for applications operating above or below this temperature.
The temperature characteristics of ceramic capacitors are those in which the capacitance changes depending on the operating temperature, and the change is expressed as a temperature coefficient or a capacitance change rate. There are two main types of ceramic capacitors, and the temperature characteristics differ depending on the type. 1.
The capacitance value of a capacitor varies with the changes in temperature which is surrounded the capacitor. Because the changes in temperature, causes to change in the properties of the dielectric. Working Temperature is the temperature of a capacitor which operates with nominal voltage ratings.

A vendor can call a capacitor X7R (or X5R or any other type) as long as it meets the temperature coefficient specs, regardless of how bad the voltage coefficient is. As an applications engineer, this fact simply reinforces the old maxim (pun intended) that any experienced apps engineer knows: "Read the data sheet!"
