Usage Precautions
- When performing dip soldering, ensure flux is fully dried to prevent quality degradation. Pay attention to the amount of flux applied.
- Do not immerse the semi-adjustable resistor in solvents. Contact us if cleaning is necessary.
- After insertion into a printed circuit board and assembly, do not apply excessive force to terminals, center terminals, or wiper contacts to avoid deformation and poor contact. Exercise particular caution with the wiper area on open-type models.
- Store away from high/low temperatures, humidity, and corrosive gases. Pay extra attention for long-term storage.
- When storing, be mindful of the stacking pressure on the products.
- Implement a First-In, First-Out (FIFO) system for inventory management.
