Usage Precautions
- Application: Temperature measurement and control.
- Measurement Error: Avoid current flowing through the thermistor chip causing self-heating and measurement errors.
- Soldering: 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.
- Environment: Avoid storage in environments with corrosive gases or direct sunlight.
- Packaging: Reseal packaging after opening.
