Bourns 3590S-2-104L Precision Trimmer Potentiometer

The Bourns 3590S-2-104L is a 10-turn, precision trimmer potentiometer with 100 kΩ resistance (104 code) designed for high-resolution calibration in analog circuits. It features linear taper (L) for proportional resistance changes and a 2 W power rating, making it suitable for calibration tasks in instrumentation, test gear, and consumer electronics. The S-2 variant uses solder-lug terminals for convenient connections and is built in a sealed body to help resist contaminants during repeated adjustments. With its 10-turn design, users can achieve fine adjustments and repeatable trim across boards or chassis, aiding offset and gain calibration in reference circuits, sensor interfaces, and audio paths. This model is part of Bourns' 3590 Precision Potentiometer family, commonly used in calibration fixtures, lab benches, and production test rigs where stable, repeatable trimming is required.
