Precautions for Use
- Ensure flux is thoroughly dried before soldering to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse semi-adjustable resistors in solvents. Contact us if cleaning is necessary.
- Avoid applying excessive force to terminals, center terminals, and wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Exercise particular caution with the wiper section on open-type models.
- Store away from high/low temperatures, high humidity, and corrosive gases. Exercise extra caution for long-term storage.
- Be mindful of the stacking quantity of products during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
