Usage Precautions
- Ensure flux is completely dry before soldering to prevent quality degradation.
- Do not immerse the potentiometer in solvents. Contact the 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. Exercise extra caution with open-type potentiometers.
- Store away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage.
- Be mindful of stacking pressure on products during storage.
- Implement a first-in, first-out (FIFO) inventory management system.
