3386S-1-102LF is a 3/8" square Trimpot trimming potentiometer from Bourns designed for precision resistance adjustment in industrial applications. This single-turn cermet potentiometer features a 1 kO resistance value with ±10% tolerance, 0.5 watt power rating at 85°C, and operates over a temperature range of -55°C to +125°C. The side adjust design (S style) provides convenient access for calibration, with a 280° nominal adjustment angle and infinite resolution. Key specifications include 500 VDC insulation resistance (1,000 MO min), dielectric strength of 900 VAC at sea level, and a temperature coefficient of ±100 ppm/°C. The LF suffix indicates 100% tin-plated terminations for RoHS compliance, making it suitable for lead-free assembly processes in instrumentation, calibration circuits, and precision adjustment applications.
