Ceramic capacitors have the advantages of good heat resistance, excellent insulation properties, simple structure, low cost, etc. However, different ceramic materials have very different characteristics, and they must be used correctly. Different capacitors have different requirements for the use of the ambient temperature. Then, if there is a problem with the use of ceramic capacitors in a low-temperature environment, you may wish to follow along with the editors.
When ceramic capacitors are used in a low-temperature environment that is below the temperature range, there are concerns about the "rate of change in capacitance", "reliability", and "temperature tolerance period." Regarding the change rate of the electrostatic capacity, for example, the temperature range of the X5R product is -55 to 85°C. Within the temperature range, the change rate of the electrostatic capacity is defined as "±15%." If the temperature exceeds the temperature range, the change in the electrostatic capacity cannot be satisfied. Rate regulations. With respect to reliability, since ceramic capacitive properties have a temperature-accelerating characteristic, there has been a tendency to strictly control high temperatures. Use below the temperature range does not reduce the reliability of the ceramic capacitor, but be careful not to cause condensation.
In use, it should be noted that the expansion of the temperature range will reduce the heat cycle, avoiding the use of a temperature environment that changes back and forth between the highest and lowest temperatures.
