Usage Precautions

Application: Temperature measurement and control.
Avoid excessive current that may cause self-heating and measurement errors.
When soldering with a soldering iron, the soldering point should be at least 2mm away from the encapsulation head. Soldering temperature should be below 360, and soldering time should be less than 3 seconds.
Storage Conditions: Temperature: -1040; Humidity: 75% RH.
Avoid storage in environments with corrosive gases and direct sunlight.
After opening the package, reseal for storage. The shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the specified items in this standard and can still be used if they meet the requirements.
If heat-shrinkable tubing is used during processing, do not use a hot air gun for shrinking. It is recommended to place the product with the heat-shrinkable tubing fitted into a constant temperature oven and shrink at 110 for 10-12 minutes.
