Bourns 3296 Series Multi-Turn Cermet Trimmer Potentiometer, 50 Ohm, 25 Turn

The Bourns 3296 Series is a family of high-quality, cermet, multi-turn trimming potentiometers designed for precise circuit adjustment in a wide range of electronic equipment. These through-hole mounted components are engineered for reliability and fine-tuning accuracy, making them ideal for applications requiring stable and repeatable resistance settings.

Featuring a robust 3/8 inch square form factor, these trimmers offer a generous 25 turns of adjustment, allowing for extremely precise calibration. The design incorporates a lead screw mechanism, available in both side and top adjustment configurations, to suit different PCB layout requirements. With an IP65 sealing rating, the potentiometer is protected against dust ingress and low-pressure water jets, enhancing its durability in challenging environments.

Key Features & Performance

• Multi-Turn Precision: The 25-turn adjustment provides excellent resolution for fine-tuning circuits, with a rotational life of 200 cycles.
• Wide Resistance Range: Available with resistance values from 10 ohm to 2Mohm, with a standard tolerance of ±10%.
• Stable Performance: A temperature coefficient of ±100ppm/°C ensures stable operation across a broad operating temperature range of -55°C to +125°C.
• Robust Construction: The cermet element and chevron seal design contribute to long-term reliability and environmental protection.
• Adequate Power Handling: With a power rating of 0.5W (500mW), it is suitable for many low-power adjustment applications.

This versatile component is a staple in electronics design, serving critical functions in calibration, offset adjustment, and setting reference voltages.
