Bourns 3266 Series 100kΩ Multi-Turn Trimmer Potentiometer

The Bourns 3266 Series trimming potentiometer is a high-quality, cermet, multi-turn component designed for precise circuit adjustment in a wide range of electronic equipment. This through-hole mount trimpot offers exceptional reliability and stability, making it an ideal choice for calibration and fine-tuning applications where accuracy is paramount.

Featuring a 1/4-inch square profile, the potentiometer provides 12 full turns of adjustment, allowing for extremely fine control over resistance values. This multi-turn capability is perfect for applications requiring precise setting, such as measuring linear distance, angle, or rotation in production and test equipment. The side or top adjustment is achieved via a lead screw mechanism.

Built for durability in demanding environments, the unit boasts an IP65 sealing rating, offering protection against dust and low-pressure water jets. It has a rotational life of 200 cycles, ensuring long-term performance. The inclusion of standoffs beneath the body allows for thorough cleaning of the printed circuit board after soldering, preventing flux contamination.

This specific model has a track resistance of 100 kilo-ohms (kΩ) with a tolerance of ±10%. It operates reliably across a wide temperature range from -55°C to +125°C, with a temperature coefficient of ±100ppm/°C. The power rating is 0.25 watts (250mW).
