The temperature of the capacitor depends on the background (or ambient) temperature (T A) of the immediate surroundings, and also on the temperature rise (ΔT) caused by self-heating. ΔT represents wasted energy. The lower its value, the longer the operational life of the capacitor and the more efficiently the circuit will operate.

6 FAQs about [Principle of Temperature Cycle of Ceramic Capacitors]
What are the temperature characteristics of ceramic capacitors?
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.
What is a temperature compensating ceramic 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).
Can a ceramic capacitor change its capacitance?
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.
What factors affect capacitance stability of MLCC ceramic capacitors?
The blog article written by Robert Lu, KYOCERA-AVX Corporation explains impact of several factors such as temperature, applied DC/AC bias voltage, and age to capacitance stability of MLCC ceramic capacitors. The multi-layer ceramic capacitor (MLCC) is one of the most common capacitor varieties found in electronic design.

What is a Class 1 ceramic capacitor?
Class 1 ceramic materials (e.g., NPO, COG) have very low temperature coefficients, meaning that their capacitance varies very little over temperature. They also have low dielectric constants, meaning that capacitors built with class 1 materials have very small capacitance per volume.
