Usage Precautions
- Purpose: Temperature measurement and control.
- Avoid excessive current that can cause self-heating and measurement errors.
- When soldering with a soldering iron, maintain a distance of at least 2mm from the encapsulation head. Soldering temperature should be below 360, and soldering time less than 3 seconds.
- Storage Temperature: -10 to 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases or direct sunlight.
- After opening the package, reseal for storage. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the specified items; if they meet the requirements, they can still be used.
- If using heat shrink tubing during processing, do not use a hot air blower for shrinking. Recommended method: Place the product with heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes for shrinking.
