Product Naming Rule
The product naming convention follows the structure: JER - 625 - V - C - R - [Resistance Code]
- JER: Series identifier
- 625: Series model
- V: Vertical mounting
- C: Dustproof seal
- R: Reverse adjustment
- Resistance Code: e.g., 101 (100), 102 (1K), 103 (10K), 104 (100K)
Usage Precautions
- Ensure flux is fully dry before soldering to prevent quality degradation. Pay attention to flux application amount.
- Do not immerse trimmer potentiometers in solvents. Contact us if cleaning is necessary.
- Avoid applying excessive force to terminals, center pins, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Exercise extra caution with the wiper section on open-type models.
- Store away from high/low temperatures, high humidity, and corrosive gases. Special attention is required for long-term storage.
- Be mindful of stacking pressure on the products during storage.
- Implement a First-In, First-Out (FIFO) inventory management system.
