Description
- The 3296W-B Cermet Trimming Potentiometer is a high-precision multiturn potentiometer engineered for industrial and professional applications. Constructed with durable cermet elements, it offers excellent stability, long-term reliability, and consistent performance under various operating conditions. With a power rating of 0.5W at 70℃, it provides a wide resistance range from 10Ω to 5MΩ, ±10% tolerance, and up to 30±2 turns of mechanical travel, enabling highly accurate calibration and adjustment.
- The bent pin design allows for flexible and secure PCB mounting, while the fully sealed structure ensures protection against dust and contaminants. Available with temperature coefficients of ±250 or ±100 ppm/°C, this RoHS compliant trimmer is ideal for use in precision instruments, communication systems, power supplies, and other critical electronic circuits.
