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.
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.
*2 Maximum operating temperature: By design, maximum ambient temperature including self-heating 20°C MAX that allows continuous use of capacitors. The EIA standard specifies various capacitance temperature factors ranging from 0ppm/°C to −750ppm/°C. Figure 1 below shows typical temperature characteristics.
You can apply maximum 10.7V to the capacitor for the entire operation temperature range to 125°C (voltage derating 20% is covered by the 33% temperature derating). Thus 16V capacitor is NOT suitable for 125°C device due to the high temperature. Need higher rated 20V tantalum polymer capacitor.
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).
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.
