Usage Precautions
Allow flux to dry thoroughly before soldering to prevent quality degradation. Control flux application volume.
Do not immerse the trimmer potentiometer in solvents. Contact for cleaning instructions if necessary.
Avoid applying excessive force to terminals, center terminals, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Exercise caution with the wiper area on open-type potentiometers.
Store away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage.
Avoid stacking products excessively during storage.
Implement a First-In, First-Out (FIFO) inventory management system.
