Usage Precautions
- Ensure flux is fully dry before soldering to prevent quality degradation.
- Do not immerse the semi-adjustable resistor in solvents. Contact manufacturer for cleaning instructions.
- Avoid applying excessive force to terminals, center pins, or wipers during PCB insertion and assembly to prevent deformation and poor contact. Pay special attention to the wiper area of open-type models.
- Store away from high/low temperatures, humidity, and corrosive gases. Take extra care for long-term storage.
- Avoid stacking products excessively during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
