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 shell. Soldering temperature should be below 360, and soldering time should be less than 3 seconds.
- If the lead wire is 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 and direct light.
- After opening the package, reseal for storage.
