Usage Precautions:
- Purpose: Temperature measurement and control.
- Avoid self-heating due to current flow through the thermistor chip, which can cause measurement errors.
- When soldering with a soldering iron, the soldering point should be at least 2mm away from the glass shell. Soldering temperature should be below 360, and soldering time should be less than 3 seconds.
- If bending lead wires, the bending point should be more than 2mm away from the glass shell to prevent damage.
- Storage temperature: -1040; Storage humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal packaging after opening.
- If using heat shrink tubing during processing, do not use a hairdryer for shrinking. It is recommended to use a constant temperature oven at 110 for 10-12 minutes for heat shrinking.
