The maximum end-of-life temperature of a thermistor depends on its specific model and manufacturing material, and in general, the common thermistor end-of-life temperature range is between 150°C and 250°C. Exceeding this temperature range will cause changes in the material structure of the thermistor, seriously affecting its performance and accuracy, and may even lead to permanent failure of the thermistor.
Therefore, when using a thermistor, the temperature must be strictly controlled to avoid exceeding its highest temperature range to ensure its normal operation and service life.
