Usage Precautions
- 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 for cleaning instructions if necessary.
- Avoid applying excessive force to terminals, center terminals, or wiper parts after insertion into PCB and assembly, as deformation can cause poor contact. Exercise caution with the wiper section, especially for open-type potentiometers.
- Store away from high/low temperatures, high humidity, and corrosive gases. Special attention is required for long-term storage.
- Be mindful of the stacking pressure on the products during storage.
- Implement a First-In, First-Out (FIFO) management system for inventory.
