Bourns 3296 Series Multi-Turn Cermet Trimmer Potentiometer 25 Turn, 200Ω

The Bourns 3296 Series comprises high-quality, cermet, through-hole trimming potentiometers. These multi-turn components are essential for precise circuit adjustments across a vast range of electronic equipment and devices, enabling accurate calibration of resistance.

A key feature is the 25-turn adjustment capability, which allows for extremely fine and repeatable tuning. The mechanism is designed for a rotational life of 200 cycles, providing reliable and consistent performance over time. The potentiometer achieves an IP65 sealing rating, protecting the sensitive internal cermet element from dust ingress and water jets, making it suitable for use in environments where exposure is a concern.

This trimmer offers a wide resistance range, from 10 ohms up to 2 megohms, with a tolerance of ±10%. It operates stably across a broad temperature spectrum from -55°C to +125°C, with a temperature coefficient of ±100ppm/°C. The power rating of 0.5W (500mW) ensures it can handle typical circuit adjustment demands. The component is available with five terminal style options and features a durable chevron seal design.

Primary Applications

These trimming potentiometers are perfectly suited for applications requiring precise measurement and control, such as calibrating linear distance sensors, adjusting rotational angles, or fine-tuning feedback in production and test equipment. Their through-hole mounting and compact 3/8-inch square profile make them easy to integrate into printed circuit board (PCB) designs where space is at a premium.
