Notes on Usage

When performing immersion soldering, ensure flux is completely dried 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.
After inserting into a printed circuit board and assembling, do not apply excessive force to terminals, the center terminal, or the 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, humidity, and corrosive gases. Pay extra attention to long-term storage.
When storing, be mindful of the stacking pressure on the products.
Manage inventory using the First-In, First-Out (FIFO) principle.
