The 3006W-1-203LF is a rectangular multiturn cermet trimming potentiometer manufactured by Bourns, designed for precision adjustment in industrial sealed applications. This device features a 20 kO resistance value (code 203) with ±10% standard tolerance, infinite resolution, and 15 turns nominal adjustment angle, enabling fine-tuned voltage and resistance adjustments of ±0.01% and ±0.05% respectively. The potentiometer operates over a temperature range of -55°C to +125°C with a power rating of 0.75 watts at 70°C, and includes solderable pins for reliable PCB integration with a low profile of only 1/4" height. Its sealed construction, U.L. 94V-0 flammability rating, and RoHS-compliant tin-plated termination (LF suffix) make it suitable for demanding industrial trimmer applications requiring long-term stability and environmental resistance.
