The 3329W-1-103LF is a 1/4" round single-turn cermet industrial trimming potentiometer (Trimpot) manufactured by Bourns, designed for precision voltage and resistance adjustment applications. This sealed unit features a 10 kO nominal resistance with ±10% tolerance, 100% tin-plated (RoHS-compliant) terminals, and a 240° nominal adjustment angle with infinite resolution. The potentiometer operates over a temperature range of -55°C to +150°C, with a power rating of 0.5 watt at 85°C (300 volts maximum), and exhibits excellent environmental performance including 1,000 megohms minimum insulation resistance at 500 VDC and 600 VAC dielectric strength at sea level. The W-style package features side-adjust configuration with standard solderable pins on 2.54 mm (0.100") centers, making it ideal for circuit board trimming, calibration, and tuning applications in industrial electronics, instrumentation, and sealed equipment where reliability and RoHS compliance are required.
