Usage Precautions
- When performing flux soldering, ensure the flux is thoroughly dried to prevent quality degradation. Pay attention to the flux application amount.
- Do not immerse the semi-adjustable resistors in solvents. Contact us if cleaning is necessary.
- After insertion into a PCB and assembly, do not apply excessive force to the terminals, center terminal, or wiper to avoid deformation and poor contact. Exercise particular caution with the wiper section on open-type models.
- Store semi-adjustable resistors away from high/low temperatures, high humidity, and corrosive gas environments. Pay extra attention during long-term storage.
- When storing, be mindful of the stacking pressure on the products.
- Manage inventory using the First-In, First-Out (FIFO) principle.
