Usage Precautions
Ensure flux is completely dry before soldering to prevent quality degradation.
Avoid immersing the potentiometer in solvents. Contact manufacturer for cleaning procedures.
Do not apply excessive force to terminals, center terminals, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Pay special attention to the wiper area on open-type models.
Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
Avoid stacking products excessively during storage.
Implement a First-In, First-Out (FIFO) inventory management system.
