Usage Precautions:
- Purpose: 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: -1040.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal for storage after opening the package.
