The 3299W-1-205LF is a 3/8" square multiturn cermet trimming potentiometer (Trimpot) designed for industrial sealed applications requiring precision resistance adjustment. This unit features a 2 megohm resistance value with ±10% tolerance, infinite resolution, and 25 turns of effective travel, enabling precise voltage and resistance adjustability of ±0.01% and ±0.05% respectively. The device is rated for 0.5 watt at 70°C and operates reliably across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C. It incorporates 100% tin-plated (RoHS-compliant) solderable pins, U.L. 94V-0 flammability rating, and meets MIL-STD-202 humidity and vibration standards. The 3299W-1-205LF is ideal for circuit calibration, signal conditioning, and precision tuning applications in industrial equipment, instrumentation, and control systems where sealed construction and long-term stability are essential.
