Important Usage Notes
- Ensure flux is thoroughly dried before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse the semi-adjustable resistors in solvents. Contact us if cleaning is necessary.
- Avoid applying excessive force to terminals, center terminals, or wiper elements after insertion into PCBs and assembly, as deformation can lead to poor contact. Exercise particular caution with open-type units.
- Store away from high/low temperatures, high humidity, and corrosive gases. Special attention is required for long-term storage.
- Be mindful of stacking pressure on the products during storage.
- Implement a first-in, first-out (FIFO) inventory management system for stock items.
