JBR-BB Wirewound Potentiometers
The JBR-BB Wirewound Potentiometer provides precise resistance adjustment from 100Ω to 100KΩ with a tight ±5% tolerance and ±0.25% independent linearity. Its robust 3600° mechanical travel ensures fine-tuned control in critical systems.
Designed for industrial use, it operates reliably from -55°C to +125°C, resists vibration and impact, and handles up to 710V—making it an excellent choice for harsh and demanding environments.
