Usage Precautions:
- Allow flux to dry thoroughly before soldering to prevent quality reduction. Pay attention to the amount of flux applied.
- Do not immerse the trimmer potentiometer in solvents. Contact 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. Exercise caution with the wiper area, especially on open-type potentiometers.
- Store away from high/low temperatures, high humidity, and corrosive gases. Pay extra attention for long-term storage.
- Be mindful of the stacking pressure on the product during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
