Product Description
Product Overview
The JER855VCR series ceramic trimmer potentiometer offers high stability, a compact size, and high precision, making it suitable for various applications. With a rated power of 0.5W and a wide resistance range, these potentiometers utilize a metal glaze element for reliable performance. Key electrical characteristics include a nominal resistance range from 300 to 2M with a 20% tolerance, a linear (B) resistance change characteristic, and a maximum operating voltage of 30VAC. The series also features low rotational noise and specific zero-resistance values depending on the nominal resistance.

Important Usage Notes
- Ensure flux is completely dry before soldering to prevent quality degradation.
- Avoid immersing the trimmer potentiometer in solvents; contact for cleaning procedures if necessary.
- Do not apply excessive force to terminals, center terminals, or wiper contacts 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 to long-term storage.
- Be mindful of stacking pressure on stored products.
- Implement a First-In, First-Out (FIFO) inventory management system.
