Usage Precautions:
- Purpose: Temperature measurement and control.
- Avoid self-heating due to current flow through the thermistor chip to prevent measurement errors.
- When soldering with an iron, the soldering point should be at least 2mm away from the glass shell. Soldering temperature should be below 360, and soldering time less than 3 seconds.
- If the lead wire is bent, the bending point should be more than 2mm away from the glass shell to avoid damaging the glass.
- Storage Temperature: -10 to 40; Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal packaging after opening.
- When using heat shrink tubing during processing, do not use a hair dryer. It is recommended to place the product with the heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes for heat shrinking.
