Precautions for use
1.Purpose of this product: temperature measurement and control;
2.Avoid the current flowing through the thermistor chip causing the component itself to heat up and cause measurement errors;
3.When soldering with a soldering iron, the soldering temperature should be lower than 300 ℃, and the soldering time should be less than 3ses ; 4.Storage temperature: -10℃～40℃; Storage humidity: ≤75% RH;
3.Avoid storing in the environment with corrosive gas and light;
6.After opening the package, it should be resealed and stored.
