Usage Precautions
- Product Use: Temperature measurement and control.
- Current Handling: Avoid excessive current that may cause self-heating and measurement errors.
- Soldering: For iron soldering, maintain a distance of at least 2mm from the film. Soldering temperature should be below 360, with a soldering time less than 3 seconds.
- Storage Conditions: Storage temperature: -1040; Storage humidity: 75% RH.
- Environment: Avoid storage in environments with corrosive gases or direct sunlight.
- Shelf Life: After opening the package, reseal for storage. Shelf life is 1 year. Products exceeding the shelf life may be re-inspected according to the standard and can be used if they meet the requirements.
- Heat Shrink Tubing: If using heat shrink tubing during processing, do not use a hot air gun for shrinking. Recommended method: Place the product with the heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes for heat shrinking.
