Why Choose JBR Trimming Potentiometers for Fine Adjustments
In precision electronics, even the smallest adjustment can make or break your design. That’s why engineers trust jb Capacitors® JBR series trimming potentiometers — a full lineup of wirewound solutions engineered for fine-tuning, stable resistance, and reliable calibration.
Built for Engineers Who Demand Accuracy
Whether you're adjusting voltage in analog circuits, calibrating sensors, or setting gain levels in amplifiers, the JBR series offers tailored solutions from single-turn to 10-turn designs, covering a wide resistance range of 50Ω to 2MΩ.
Each model is optimized for precise mechanical control, featuring:
- Smooth adjustment torque (as low as 3.5 mN·m)
- Independent linearity down to ±0.25%
- Long rotational life (up to 10,000 cycles)
- High voltage and insulation resistance (up to 1GΩ)
Which Model Fits Your Application?
| Model | Turns | Power Rating | Linearity | Notable Feature |
|---|---|---|---|---|
| JBR-BA | 10-turn | 2W | ±0.5% | Ultra-precise tuning stroke |
| JBR-BB | Multi-turn | 2W | ±0.25% | High accuracy + wide temp range |
| JBR-BC | Single-turn | 1W | ±10% | Up to 2MΩ resistance for broad applications |
| JBR-BD | Single-turn | 1W | ±10% | Compact with simple 270° angle |
| JBR-BE | Single-turn | 1W | ±0.3% | Lower power rating for stable control |
| JBR-BF / BG | Lock type | 2W | ±0.3% | Withstand vibration and repeated setting |
