Precision control in electronic design is no longer optional—it is essential.
Whether you’re working in industrial automation, instrumentation, or critical sensing applications, achieving consistent and accurate resistance adjustments can directly affect the long-term performance of your circuit. Engineers seeking stability over time, even under environmental stress, are increasingly looking to multiturn potentiometers to fill this role.

Understanding the Problem: Instability in Adjustment

Single-turn trimmers, while compact, often lack the resolution and durability needed for high-precision circuits. When subjected to thermal cycling, vibration, or prolonged use, they can experience resistance drift, poor repeatability, and unpredictable long-term behavior. These issues can introduce noise or compromise calibration, leading to costly system downtime or performance deviation.

The Multiturn Advantage

The jb JBR-3296 series addresses these challenges with a multiturn design that offers 25 ±2 turns of effective electrical travel. This allows for more granular control and repeatable precision, particularly in circuits requiring sensitive calibration or voltage division. The extended travel range also reduces the likelihood of over-adjustment, a common issue in single-turn units.

Cermet Material: Stability by Design

One of the defining characteristics of the JBR-3296 is its cermet (ceramic-metal) resistive element. Cermet materials offer excellent temperature stability, low noise, and minimal aging effects, ensuring that resistance values remain consistent over time. This stability is critical in mission-critical systems where reliability cannot be compromised.

Sealed Construction for Harsh Conditions

Beyond internal precision, the JBR-3296 is engineered for reliability in adverse environments. Its sealed housing design protects against moisture, dust, and contaminants, significantly extending operational lifespan. The device maintains electrical integrity across a temperature range of -55°C to +125°C, and has been tested to withstand both vibration and shock conditions common in industrial and automotive settings.

Designed for Layout Flexibility

The JBR-3296 series is available in five terminal configurations (W, Y, P, X, Z), enabling engineers to optimize PCB layout based on space, orientation, and routing requirements. This adaptability is particularly useful when designing within tight enclosures or complex multi-board systems.
