Usage Precautions
- Application: Temperature measurement and control.
- Avoid self-heating of the component due to current flow, which can cause measurement errors.
- When soldering with a soldering iron, maintain a distance of at least 2mm from the glass housing. Soldering temperature should be below 360, and soldering time less than 3 seconds.
- If bending lead wires, the bend point should be more than 2mm away from the glass housing to prevent damage.
- Storage Temperature: -10 ~ 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases or direct sunlight.
- Reseal packaging after opening for storage.
