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