The 3299X-1-103 is a 3/8" square multiturn cermet trimming potentiometer designed for industrial sealed applications with five popular terminal styles and standoff options. This device features a resistance range of 10 ohms to 2 megohms with ±10% standard tolerance, infinite resolution, and 25 turns of effective travel for precise voltage and resistance adjustability of ±0.01% and ±0.05% respectively. The potentiometer operates across a temperature range of -55°C to +125°C with a power rating of 0.5 watts at 70°C, 1,000 megohms minimum dielectric strength, and 900 VDC sea level dielectric strength. It exhibits excellent environmental performance with 200 rotational cycles, 1,000 hours load life at 0.5 watts, and compliance with MIL-STD-202 humidity and vibration standards. The 3299X-1-103 is ideal for precision trimming applications in instrumentation, signal processing, and industrial control systems where reliability and long-term stability are essential.
