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.
1. Temperature-compensating-type multilayer ceramic capacitors (Class 1 in the official standards) This type uses a calcium zirconate-based dielectric material whose capacitance varies almost linearly with temperature. 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).
For this reason, the electrostatic capacitance vs. temperature characteristic standard values are specified by the maximum and minimum values of the capacitance change rate within the applied temperature range, relative to the capacitance value C 25 at the reference temperature *7. (See Equation 2.) *7 Based on EIA standard of 25°C
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.
Some capacitors are linear (class 1 capacitors), these are highly stable with temperatures; such capacitors have a zero temperature coefficient. Generally Mica or Polyester capacitors are examples for the Class 1 capacitors.
