The 3352E-1-502LF is a 3/8" round Trimpot® trimming potentiometer manufactured by Bourns, designed for industrial and open-frame applications requiring precise resistance adjustment. This single-turn device features a stable cermet element with infinite resolution, 5 kO nominal resistance (code 502), and a top-adjust configuration with thumb and screwdriver adjustment capability. The potentiometer offers voltage divider adjustability of ±0.05%, an adjustment angle of 205° nominal, and operates reliably across a temperature range of -55°C to +125°C with a power rating of 0.50 watts at 85°C. The unit is RoHS compliant with 100% tin-plated terminations (LF designation), making it suitable for precision instrumentation, signal conditioning, and calibration applications where stable, repeatable resistance values are essential.
