The 3386V-1-504LF is a 3/8" square Trimpot® trimming potentiometer manufactured by Bourns, designed for precision adjustment in industrial applications. This single-turn cermet device features a 500 kO resistance value with ±10% standard tolerance and infinite resolution, enabling precise voltage divider adjustments with ±0.05% accuracy. The potentiometer operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watts at 85°C. The top-adjust 3386V model includes a sealed design with 280° nominal adjustment angle, 5.0 oz-in maximum torque, and RoHS-compliant 100% tin-plated terminations. This component is ideal for instrumentation, signal conditioning, and calibration circuits where reliable, repeatable adjustment is required.
