Bourns 3266 Series 100kΩ Multi-Turn Trimmer Potentiometer

The Bourns 3266 Series Trimmer Potentiometer is a multi-turn cermet component with a 100kΩ track resistance, designed for precise circuit adjustment across a wide range of electronic equipment.

Overview

This through-hole trimpot has a 1/4-inch square profile and provides 12 full turns of adjustment, allowing fine control over resistance values. The side or top adjustment is achieved via a lead screw mechanism. The multi-turn design suits calibration and fine-tuning applications where accuracy is required, such as measuring linear distance, angle, or rotation in production and test equipment.

Key Features

• IP65 sealing rating, providing protection against dust and low-pressure water jets
• Rotational life of 200 cycles
• Standoffs beneath the body allow thorough cleaning of the printed circuit board after soldering, preventing flux contamination
• Track resistance of 100kΩ with a tolerance of ±10%
• Power rating of 0.25W (250mW)
• Operating temperature range from -55°C to +125°C
• Temperature coefficient of ±100ppm/°C

Specifications

Constructed with a cermet element, the potentiometer has 12 turns and measures 33mm (W) x 43mm (H) x 15mm (D), with a weight of 0.43 grams. This trimmer potentiometer suits precise adjustment in electronic equipment where a multi-turn cermet trimpot with a 100kΩ track resistance and IP65 sealing is required.
