Compact and Stable: JBR Series Trimmers for Circuit Tuning

Modern electronics demand components that are both compact and reliable. As PCBs get smaller and applications more complex, trimming potentiometers have become essential for ensuring accurate and stable circuit tuning.

The JBR Series from jb Capacitors is designed to meet this challenge, combining miniature size with stable electrical performance.

1. Compact Designs for Space-Constrained Applications

For handheld devices, communication modules, or IoT hardware, board space is always limited. The JBR-065 model solves this by offering a miniature footprint with top-adjust design — making precise tuning possible even in tight layouts.

Common applications:

  • Wireless transmitters and receivers
  • Medical devices with limited enclosure space
  • Compact consumer electronics requiring fine tuning

2. Stable Electrical Performance Over Time

Size alone is not enough — stability matters. The JBR-3309, a sealed general-purpose trimmer, maintains consistent resistance values even after repeated adjustments. Its sealed design resists moisture and dust, making it ideal for high-humidity or field applications.

Key features across the series:

  • Tight resistance tolerance
  • Low rotational torque for smooth adjustment
  • Excellent aging characteristics

3. Built for Real-World Engineering Needs

The JBR series is developed with practical engineering requirements in mind:

  • Resistance range from 10Ω to 2MΩ
  • Through-hole mounting for robust mechanical reliability
  • Top or side adjustment options for flexible layouts
  • Up to 200 mechanical adjustment cycles

These trimmers are widely used for offset voltage tuning, gain control, and other fine adjustments in analog and mixed-signal circuits.

Precision Meets Durability – jb JBR-3296 Potentiometers for Critical Adjustments

  In modern electronics, the demand for both precision and reliability is higher than ever. When every micro-adjustment matters and environmental stress can compromise performance, engineers turn to components that won’t let them down. That’s where the jb JBR-3296 multiturn cermet potentiometer stands out.

Engineered for Critical Adjustments

The JBR-3296 series offers a 25 ±2 turn range, allowing highly accurate and repeatable adjustments in sensitive circuits. Unlike standard single-turn trimmers, this multiturn design enables superior fine-tuning, making it ideal for industrial control, measurement instruments, and high-precision applications.

Reliable Stability with Cermet Technology

Constructed with cermet (ceramic-metal) material, the JBR-3296 ensures minimal resistance drift even under temperature fluctuations. Engineers value this stability in circuits where long-term precision is essential.

Sealed for Harsh Environments

Its sealed package design prevents dust, moisture, and contaminants from affecting internal components. With an operational temperature range from -55°C to +125°C and compliance with shock and vibration standards, the JBR-3296 is fully qualified for demanding industrial environments.

Multiple Terminal Styles for Flexible Layout

Available in five terminal styles (W, Y, P, X, Z), the JBR-3296 gives designers layout flexibility for various PCB configurations. This versatility streamlines the design process without sacrificing reliability or functionality.

Key Technical Highlights

  • Resistance range: 10Ω to 5MΩ
  • Tolerance: ±10% (±20% for 10Ω, 20Ω, and 2MΩ)
  • Power rating: 0.5W @ 70°C, derated to 0W @ 125°C
  • Insulation resistance: ≥1GΩ @ 500V DC
  • Withstand voltage: 640VAC
  • Temperature coefficient: ±250ppm/°C (optional ±100ppm/°C)
  • Rotational life: 200 cycles

Why Choose jb JBR-3296?

The JBR-3296 offers a balanced solution of precision, durability, and design flexibility. Whether you're designing for industrial machinery, signal processing, or test equipment, this potentiometer ensures accurate control with long-lasting performance.
