| Precautions for Use | |
| Soldering Flux | Ensure flux is fully dry before soldering to prevent quality degradation. Control flux application amount. |
| Cleaning | Do not immerse potentiometers in solvents. Contact manufacturer for cleaning procedures if necessary. |
| Handling | Avoid applying 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 potentiometers. |
| Storage Environment | Avoid high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage. |
| Stacking | Be mindful of the stacking pressure on the products during storage. |
| Inventory Management | Implement a First-In, First-Out (FIFO) system for inventory. |
