The 3059J-1-502LF is a 1-1/4" rectangular multiturn cermet trimming potentiometer manufactured by Bourns, designed for precision adjustment in industrial sealed applications. It features a 5 kO resistance value with ±10% tolerance, 22 turns of effective travel, and infinite resolution for fine-tuning capabilities. The device operates across a temperature range of -55°C to +150°C with a power rating of 1.0 watt at 70°C, 1,000 MO minimum insulation resistance at 500 VDC, and dielectric strength of 900 VAC at sea level. The potentiometer includes flexible leads (7 strands of 30 AWG), solderable printed circuit pins, and is RoHS compliant with 100% tin plating. This component is ideal for precision calibration, signal conditioning, and circuit tuning in industrial instrumentation, data acquisition systems, and sealed electronic assemblies where reliability and environmental protection are essential.
