Capacitor capacitance temperature
Capacitor Characteristics
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.

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.

6 FAQs about [Capacitor capacitance temperature]
What is the temperature of a capacitor?
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.
How does temperature affect the capacitance of a capacitor?
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.
