Usage Precautions

Intended Use: Temperature measurement and control.
Avoid excessive current that may cause self-heating and measurement errors.
For soldering, maintain a distance of at least 2mm from the film. Soldering temperature should be below 360, with a duration of less than 3 seconds.
Storage Conditions: Temperature: -10 ~ 40; Humidity: 75% RH.
Avoid storage in environments with corrosive gases or direct sunlight.
Reseal packaging after opening and store. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the standard requirements and can still be used if they meet the requirements.
When using heat shrink tubing during processing, do not use a hot air gun for shrinking. Recommended process: Place the product with the heat shrink tubing into a constant temperature oven and heat shrink at 110 for 10-12 minutes.
