Usage Precautions
- Allow flux to dry thoroughly before soldering to prevent quality degradation. Pay attention to flux application amount.
- Do not immerse the semi-adjustable resistors in solvents. Contact for cleaning instructions if necessary.
- Avoid applying excessive force to terminals, center terminals, and wiper parts after PCB insertion and assembly to prevent deformation and poor contact. Exercise caution with the wiper area, especially on open types.
- Store away from high/low temperatures, humidity, and corrosive gases. Pay extra attention for long-term storage.
- Be mindful of stacking pressure on the products during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
