Usage Precautions:
- Purpose: Temperature measurement and control.
- Avoid self-heating due to current flow through the thermistor chip, which can cause measurement errors.
- When soldering with an iron, the soldering point should be at least 2mm away from the glass end. 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 end to prevent glass damage.
- Storage temperature: -10 to 40; Storage humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal packaging after opening.
