3386B-1-201LF is a 3/8" square single-turn cermet trimming potentiometer designed for industrial applications requiring precise resistance adjustment. It features a 200 ohm resistance value with ±10% tolerance, a power rating of 0.5 watt at 85°C, and operates over a temperature range of -55°C to +125°C. The side adjust configuration (Model B) includes solderable pins with 5.97 mm diameter, a mechanical angle of 310° nominal, and adjustment angle of 280° nominal. This sealed potentiometer offers infinite resolution, 1000 megohms minimum insulation resistance at 500 VDC, and meets UL 94V-0 flammability standards. The LF suffix indicates 100% tin-plated RoHS compliant terminations, making it suitable for lead-free assembly processes in precision trimming applications.
