• [Resistance Code]: Indicates nominal resistance (e.g., 101 for 100, 102 for 1K, 103 for 10K)

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.
