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.
