Precautions for Use:

Ensure flux is completely dry before soldering to prevent quality degradation.
Do not immerse the semi-adjustable resistor in solvents. Contact us if cleaning is necessary.
Avoid applying excessive force to terminals, center terminals, or wiper contacts after insertion into PCBs and assembly, as this can cause deformation and poor contact, especially for open types.
Store away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage.
Avoid stacking products excessively during storage.
Implement a First-In, First-Out (FIFO) inventory management system.
