Instructions for Use:

1. Handling:

   • Handle with care to avoid mechanical damage.
   • Avoid touching the resistor body directly; use tweezers or other tools.

2. Soldering:

   • Preheat the PCB to reduce thermal shock.
   • Use a soldering iron with a temperature of 300掳C to 350掳C.
   • Solder each terminal for no more than 3 seconds.
   • Allow the resistor to cool naturally after soldering.

3. Mounting:

   • Ensure the resistor is placed correctly on the PCB according to the circuit diagram.
   • Verify the orientation if applicable (though most chip resistors are non-polarized).

4. Testing:

   • After mounting, use a multimeter to verify the resistance value.
   • Check for any shorts or opens in the circuit.

5. Storage:

   • Store in a dry, cool place away from direct sunlight.
   • Keep in anti-static packaging if not in immediate use.

6. Environmental Considerations:

   • Ensure the operating environment does not exceed the specified temperature range.
   • Avoid exposure to corrosive substances or high humidity.
