| Usage Precautions | |
| Soldering Flux | Ensure flux is thoroughly dried after application to prevent quality degradation. Pay attention to the amount of flux applied. |
| Cleaning | Do not immerse semi-adjustable resistors in solvents. Contact us if cleaning is necessary. |
| Handling | Avoid applying excessive force to terminals, center terminals, or wiper parts during PCB insertion and assembly to prevent deformation and poor contact. Exercise particular caution with the wiper mechanism on open-type units. |
| Storage Environment | Avoid high and low temperatures, high humidity, and corrosive gas environments. Pay extra attention to long-term storage. |
| Stacking | Be mindful of the stacking weight on the products during storage. |
| Inventory Management | Employ a First-In, First-Out (FIFO) system for inventory management. |
