However, too rapid temperature rise may cause unexpected failures to the NTC thermistor, please do not apply more than 10mW of electric power to it in short time (10mW of power will increase the temperature of the NTC thermistor by about 10℃). The current less than 1/10 of the Permissive Operating Current value is recommended in order to prevent selfheating of the NTC thermistor.
