The ATH10K1R25 is a compact high precision glass encapsulated thermistor, its size is 1.25mm in diameter. Comparing with conventional epoxy encapsulated thermistors, the ATH10K1R25 thermistor features much higher long term stability and wider operating temperature range. The small size results in short response time. This thermistor works well with our TEC controllers and TEC modules.
