Wirewound Potentiometers JBR-BA ~ JBR-BG Series | jb Capacitors
When engineers seek precision control, the wirewound potentiometer is their trusted choice. The jb® JBR Series — models JBR-BA through JBR-BG — delivers accurate and stable resistance adjustment across industrial, audio, and laboratory systems. From single-turn trimmers to 10-turn calibration potentiometers, every detail is built for consistency, durability, and smooth torque operation.
Why Choose Wirewound Potentiometers
A wirewound potentiometer uses a coiled resistance wire instead of carbon film, offering: • Linearity within ±0.5% for exact voltage tracking • Low temperature drift (±100 ppm/°C) • High power handling up to 2 W • Extended lifetime beyond 10,000 cycles. These features ensure stable calibration and signal reliability under heat or vibration.
JBR Series Overview
The jb® JBR Series includes several wirewound potentiometer types — from compact PCB trimmers to rugged multi-turn units. Engineers can select by turns, torque, or mounting style to match their control system requirements.
| Series | Turns | Power | Resistance Range | Application |
|---|---|---|---|---|
| JBR-BC | 1 Turn | 1 W | 50 Ω – 2 MΩ | PCB trimming and calibration |
| JBR-BD | 1 Turn | 1 W | 50 Ω – 10 kΩ | Panel knob adjustment |
| JBR-BE | 5 Turns | 1 W | 100 Ω – 47 kΩ | Compact control modules |
| JBR-BA / BB / BF / BG | 10 Turns | 2 W | 100 Ω – 100 kΩ | Calibration & automation systems |
Performance in Real Applications
In precision power supplies and servo controllers, even a 0.1 V variation can impact system stability. The jb® wirewound potentiometer maintains consistent resistance and smooth rotation, providing accurate feedback for calibration and control circuits.
