Instructions for Use

1. Handling and Storage:

   • Store in a dry, cool place.
   • Handle with care to avoid mechanical damage.

2. Soldering:

   • Preheat the board to 120°C to 150°C.
   • Use a soldering iron with a temperature of 260°C to 300°C.
   • Soldering time should not exceed 3 seconds per joint.
   • Allow the device to cool naturally after soldering.

3. Mounting:

   • Ensure the thermistor is securely mounted on the PCB.
   • Avoid excessive mechanical stress on the leads.

4. Operation:

   • Ensure the operating temperature does not exceed the maximum rating.
   • Monitor the current to ensure it does not exceed the maximum steady state current.
   • For pulse applications, ensure the energy rating is not exceeded.

5. Testing:

   • Measure the resistance at room temperature to verify it is within the nominal range.
   • Test the thermal response by applying a known current and measuring the temperature rise.

6. Disposal:

   • Follow local regulations for the disposal of electronic components.
   • Recycle where possible.
