Usage Precautions
- Intended Use: Temperature measurement and control.
- Measurement Accuracy: Avoid current flow through the thermistor chip that causes self-heating, which can lead to measurement errors.
- Soldering: When soldering with a soldering iron, the soldering point should be at least 2mm away from the coating layer. Soldering temperature should be below 300, and soldering time should be less than 3 seconds.
- Storage Conditions: Storage temperature: -10 to 40; Storage humidity: 75% RH.
- Environmental Considerations: Avoid storage in environments with corrosive gases and direct sunlight.
- Packaging: Reseal and store properly after opening the package.
