Usage Precautions
Application: Temperature measurement and control.
Avoid current flowing through the thermistor chip causing self-heating and measurement errors.
When soldering with an iron, the soldering point should be at least 2mm away from the coating layer. Soldering temperature should be below 300, and soldering time less than 3 seconds.
Storage Temperature: -10 to 40.
Storage Humidity: 75% RH.
Avoid storage in environments with corrosive gases or direct sunlight.
Reseal packaging after opening.
