DESCRIPTION

The 3329H-1-503 is a 1/4" round single-turn cermet trimming potentiometer (Trimpot) manufactured by Bourns, designed for industrial sealed applications requiring precision resistance adjustment. This model features a 50 kO standard resistance value with ±10% tolerance, infinite resolution, and an adjustment angle of 240° nominal, providing fine-tuning capability for circuit calibration. The potentiometer operates across a wide temperature range from -55°C to +150°C with a temperature coefficient of ±100 ppm/°C, and delivers 0.5 watts power rating at 85°C (maximum 300 volts). Key electrical characteristics include 1,000 megohms minimum insulation resistance at 500 VDC, 600 VAC dielectric strength at sea level, and contact resistance variation of 3.0% or 3 ohms maximum. The device is sealed, RoHS compliant, and qualified per MIL-PRF-22097 (style RJ50) and MIL-PRF-39035 (style RJR50), making it suitable for demanding applications in instrumentation, industrial control systems, and military/aerospace equipment where reliability and environmental resistance are critical.
