Usage Precautions
- Allow flux to dry thoroughly before soldering to prevent quality degradation.
- Do not immerse the trimmer potentiometer in solvents. Contact manufacturer for cleaning instructions.
- 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.
- 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.
