| Usage Precautions | |
| A. Ensure flux is thoroughly dried before soldering to prevent quality degradation. Pay attention to flux application amount. | |
| B. Do not immerse semi-adjustable resistors in solvents. Contact us for cleaning procedures if necessary. | |
| C. Avoid applying excessive force to terminals, center pins, or wipers during PCB insertion and assembly to prevent deformation and poor contact, especially on open-type models. | |
| D. Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage. | |
| E. Be mindful of stacking pressure on products during storage. | |
| F. Implement First-In, First-Out (FIFO) inventory management. | |
