Usage Notes

Primary Use: Temperature measurement and control.
Avoid excessive current that causes 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, with a soldering time less than 3 seconds.
Storage Temperature: -10 ~ 40.
Storage Humidity: 75% RH.
Avoid storage in environments with corrosive gases or direct light.
After opening the package, reseal for storage. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the standard and can still be used if they meet the requirements.
If using heat shrink tubing during processing, do not use a hairdryer for shrinking. Recommended method: place the product with heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes.
