AI Customer ServiceThe 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 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.
*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.
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).
Film capacitors can also be affected by internal stresses due to pressure changes. This can take the form of capacitance changes as well as low insulation resistance. All capacitors listed in this data book can be stored at any temperature within the entire category temperature range for short periods.
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.
