Important Usage Notes:
- Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse the trimmer potentiometer in solvents. Contact manufacturer for cleaning procedures if necessary.
- 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 designs.
- Store in a location away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage conditions.
- Be mindful of stacking weight when storing products.
- Implement a First-In, First-Out (FIFO) inventory management system.
