The 3352T-1-201 is a single-turn cermet trimming potentiometer featuring a 3/8" round open-frame design with thumb and screwdriver adjustment capability. It offers infinite resolution with a stable cermet element, adjustability of ±0.05% in voltage divider mode and ±0.25% in rheostat mode, and operates across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C for resistances 2K and above. The device is rated for 0.50 watts at 85°C with a maximum voltage rating of 250 volts, and features a mechanical angle of 250° nominal with a rotational life of 200 cycles at 3% resistance tolerance. This trimmer is ideal for precision calibration and adjustment in industrial instrumentation, data acquisition systems, and control circuits where stable, fine-tuning performance is required.
