The 3329W-1-502LF is a 1/4" round single-turn cermet industrial trimming potentiometer (Trimpot) manufactured by Bourns, designed for precision voltage and resistance adjustment in sealed applications. This unit features a 5,000 ohm resistance value with ±10% tolerance, infinite resolution, and a 240° nominal adjustment angle with 260° mechanical angle, providing smooth and reliable tuning capabilities. The potentiometer operates over a temperature range of -55°C to +150°C with a power rating of 0.5 watt at 85°C, and includes solderable pins with 100% tin-plated (RoHS compliant) termination. It exhibits excellent electrical stability with ±0.05% adjustability for voltage and ±0.15% for resistance, along with 1,000 megohms minimum insulation resistance at 500 VDC. The 3329W-1-502LF is commonly used in industrial control circuits, instrumentation, and sealed applications where precision trimming and environmental protection are essential, with standard packaging of 50 pieces per tube.
