Product Naming Convention
The product naming convention follows the structure: JER 655 H C [Resistance Code]
- JER: Series identifier
- 655: Model number
- H: Mounting form (e.g., Horizontal)
- C: Structure (e.g., Dustproof Seal)
- [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.
