Precautions for Use

When performing immersion soldering, ensure flux is thoroughly 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.
When inserting into PCBs and assembling, avoid applying excessive force to terminals, sliders, or wiper contacts to prevent 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 gases. Pay extra attention for long-term storage.
When storing, be mindful of the stacking pressure on the products.
For inventory management, adhere to the First-In, First-Out (FIFO) principle.
