The Temperature Coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. The temperature coefficient of a capacitor is generally expressed linearly as parts per million per degree centigrade (PPM/ o C), or as a percent change over a particular range of temperatures.

The table below shows the difference between the operating temperature range and the applicable temperature range given in the detailed specifications sheet for the multilayer ceramic capacitors (MLCCs).
Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte. The higher cold resistivity increases the capacitor''s ESR 10 to 100 fold and reduces the available capacitance.
Working Temperature is the temperature of a capacitor which operates with nominal voltage ratings. The general working temperatures range for most capacitors is -30°C to +125°C. In plastic type capacitors this temperature value is not more than +700C.

In plastic type capacitors this temperature value is not more than +700C. The capacitance value of a capacitor may change, if air or the surrounding temperature of a capacitor is too cool or too hot. These changes in temperature will cause to affect the actual circuit operation and also damage the other components in that circuit.
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.
Largely the formation voltage sets the high-temperature limit. Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte.
Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties. If the air or surrounding temperature becomes to hot or to cold the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit.
For long periods of storage keep capacitors at cool room temperatures and in an atmosphere free of halogen gases like chlorine and fluorine that can corrode aluminum. Storage temperature ranges are from –55 ºC to the upper limit of the operating-temperature ranges. Sources: Capacitor Selection Guide - KEMET (.PDF)
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
