The 3339H-1-204 is a four-turn cermet trimming potentiometer featuring a unique planetary drive mechanism that enables precise wiper setting of a multiturn adjustment in a single-turn package size. This sealed industrial-grade component offers a standard resistance range from 10 ohms to 1 megohm with ±10% tolerance, infinite resolution, and exceptional adjustability of ±0.05% voltage and ±0.1% resistance. The device operates across a temperature range of -55°C to +150°C with a temperature coefficient of ±100 ppm/°C, delivers 0.5 watts at 85°C (maximum 300 volts), and provides 1,000 megohms minimum insulation resistance at 500 VDC. With its top-adjust style, solderable pins, 3 oz-in maximum torque, and RoHS-compliant options available, the 3339H-1-204 is ideal for precision circuit tuning applications in industrial equipment, instrumentation, and consumer electronics requiring reliable long-term performance.
