The 3329X-1-103LF is a 1/4-inch round single-turn cermet industrial trimming potentiometer (Trimpot) designed for precision resistance adjustment in sealed applications. It features a 10 kO nominal resistance with ±10% tolerance, infinite resolution, and 240° adjustment angle, delivering ±0.15% resistance adjustability and ±0.05% voltage adjustability. The device is rated for 0.5 watt at 85 °C (maximum 300 volts), operates across -55 °C to +150 °C, and meets MIL-PRF-22097 and MIL-PRF-39035 specifications with 100% tin-plated RoHS-compliant termination. It withstands 600 VAC dielectric strength at sea level, 1000 MO minimum insulation resistance at 500 VDC, and is sealed for reliability in harsh industrial environments. Common applications include precision calibration, signal conditioning, and equipment tuning in aerospace, military, and industrial control systems.
