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 glass shell. Soldering temperature should be below 360, and soldering time less than 3 seconds.
- If leads are bent, the bending point should be more than 2mm away from the glass shell to prevent damage.
- Storage Temperature: -10 to 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases or direct sunlight.
- Reseal packaging after opening.
