The 3299X-1-205 is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications. This model features a 2 megohm resistance value 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 device operates across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watt at 70°C (maximum 300 volts). The 3299X terminal style provides solderable pins with 1.91 mm (0.075") spacing, and the unit meets UL 94V-0 flammability standards with RoHS-compliant tin-plated terminations available. This trimmer is ideal for precision circuit calibration, signal conditioning, and equipment tuning applications where compact size, reliability, and fine adjustment capability are essential.
