Product Naming Rule
The product naming convention is JER-855-V-C-XXX, where:
- JER: Series
- 855: Model
- V: Vertical Mounting
- C: Dustproof Sealing
- XXX: Resistance Code (e.g., 101 for 100, 102 for 1K, 103 for 10K)
Usage Precautions
- Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to flux application amount.
- Do not immerse the semi-adjustable resistor in solvents. Contact us for cleaning instructions if necessary.
- Avoid applying excessive force to terminals, center terminals, or wiper parts during PCB insertion and assembly to prevent deformation and poor contact, especially with open-type models.
- Store away from high/low temperatures, high humidity, and corrosive gases. Pay extra attention for long-term storage.
- Be mindful of stacking pressure on the products during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
