Instructions for Use:

1. Handling: Handle the resistor with care to avoid physical damage. Use appropriate tools and techniques when soldering.
2. Soldering: Preheat the PCB to reduce thermal shock. Use a soldering iron with a temperature between 300°C to 350°C. Apply solder to the pads, not directly to the resistor.
3. Placement: Ensure the resistor is placed flat on the PCB with the leads aligned with the pads. The orientation of the resistor does not matter as it is non-polarized.
4. Inspection: After soldering, inspect the joints for proper wetting and absence of shorts or bridges.
5. Storage: Store in a dry, cool place to prevent moisture absorption which can affect performance.
6. Marking: The mark code "222" indicates a resistance value of 2.2KΩ. The first two digits (22) represent the significant digits, and the third digit (2) represents the number of zeros following the significant digits.
7. Testing: Use a multimeter to verify the resistance value before and after installation to ensure it meets the specified tolerance.
