When precision matters in your PCB designs, a reliable trimming potentiometer can make all the difference. Whether you're fine-tuning signal levels, adjusting offset voltages, or balancing bridge circuits, selecting the right trimmer is essential.

So, what makes the JBR series from jb Capacitors a standout option?

1. Stable and Accurate Tuning

JBR trimmers maintain stable resistance over time, even under changing environmental conditions. With tight resistance tolerance and low noise characteristics, they’re ideal for applications that require exact calibration and minimal drift.

• Audio circuit adjustments requiring low-noise operation
• Sensor calibration in IoT and control systems
• Offset tuning in precision analog circuits

2. Versatile Form Factors for Diverse Layouts

The JBR family includes several models tailored for different needs:

• JBR-065 – For ultra-compact devices and space-limited PCB layouts (Download PDF)
• JBR-3309 – A sealed, general-purpose model for standard applications (Download PDF)
• JBR-3540 – Wire-wound structure for high-precision and high-voltage designs (Download PDF)

Each model offers top or side adjustment to suit different layout needs.

3. Proven Reliability for Demanding Environments

Designed for professionals, JBR series trimmers offer:

• Rotation life up to 200 cycles
• High insulation resistance and dielectric strength
• Sealed housing against moisture and dust

These features make them suitable for prototyping, industrial designs, and large-scale manufacturing.

Quick Guide to Selecting a Trimmer

Key factors to consider when choosing a trimmer potentiometer:

• Resistance range and tolerance
• Power rating and voltage capacity
