The 3329H-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 resistance value with ±10% tolerance, 100% tin-plated (RoHS-compliant) solderable pin terminals, and an adjustment angle of 240° nominal 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 demonstrates excellent stability with a temperature coefficient of ±100 ppm/°C. It is qualified to MIL-PRF-22097 (style RJ50) and MIL-PRF-39035 (style RJR50) standards, making it suitable for industrial, military, and high-reliability applications requiring precise tuning and long-term performance.
