Usage Precautions

Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
Do not immerse the trimmer potentiometer in solvents. Contact us if cleaning is necessary.
Avoid applying excessive force to terminals, center terminals, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact, especially with open-type designs.
Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
Be mindful of the stacking pressure on the products during storage.
Implement a First-In, First-Out (FIFO) inventory management system.
