JBR-BB Wirewound Potentiometers

The JBR-BB Trimming Potentiometers deliver accurate resistance adjustments within a range of 100Ω to 100KΩ, with a tolerance of ±5%. Designed for durability, they operate in temperatures from -55°C to +125°C and have a robust 3600° mechanical travel. These potentiometers are well-suited for industrial settings, handling high vibrations, impacts, and extreme conditions efficiently.
