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.
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 EIA and JIS standards state that within the operating temperature range, the change in capacitance will not exceed the specified tolerance. The chemical composition of the ceramic is not a part of the standard. Manufacturers of capacitors use different additives to the dielectrics in order to change the performance of the capacitors.
If the surrounding temperature becomes too hot or too cold the capacitance value of the circuit may not operate properly. Generally, most capacitors work well between -30oC to +125oC. Nominal voltage ratings for a working temperature for plastic capacitor types are no more than +70oC.
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.
