The 3299X-1-201LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications. This device features a 200 ohm resistance value with ±10% tolerance, infinite resolution, and 25 turns of effective travel for precise voltage and resistance adjustments (±0.01% voltage adjustability, ±0.05% resistance adjustability). It 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 dielectric strength at sea level. The unit is RoHS compliant with 100% tin-plated terminations (LF designation), features solderable pins, and includes mechanical stops with a wiper set at 50% of actual travel resistance. Common applications include precision circuit tuning, signal conditioning, and calibration in industrial control systems, instrumentation, and sealed electronic assemblies where reliability and environmental protection are essential.
