Usage Notes
- Ensure flux is fully dried before soldering to prevent quality degradation.
- Do not immerse the semi-adjustable resistor in solvents. Contact us for cleaning procedures if necessary.
- Avoid applying excessive force to terminals, center terminals, or wiper elements during PCB insertion and assembly to prevent deformation and poor contact, especially with open-type models.
- Store away from high/low temperatures, high humidity, and corrosive gases. Pay extra attention for long-term storage.
- Be mindful of stacking pressure on the product during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
