Generally, when using a capacitor, only the capacity and withstand voltage of the capacitor are considered, and the influence of temperature on the capacitor is not considered. In fact, many parameters of capacitance are closely related to temperature. Therefore, when using capacitors, you should pay attention to the effect of temperature on capacitance. Especially when designing precision circuits and long-life circuits, you should fully consider the relationship between temperature and capacitance. 1. Temperature and life of capacitance. Under normal circumstances, the life of a capacitor decreases with increasing temperature, the most obvious being an electrolytic capacitor. An electrolytic capacitor with a limit working temperature of 85℃, when working at a temperature of 20℃, generally can guarantee a normal working time of 181019 hours; and when working at a limit temperature of 85℃, it can generally only guarantee 2000 Hours of normal working time. Therefore, you should pay attention to this situation when designing the circuit.
