The 72PMR1KLF is a single-turn trimmer potentiometer from BI Technologies' Model 72 series, featuring a 3/8" square cermet element designed for precision resistance adjustment. It offers a standard resistance range of 10 ohms to 2 megohms with ±10% tolerance (±20% for values below 100 ohms), and supports a maximum input voltage of 200 Vdc or rms with a power rating of 0.5 watts at 85°C. The device provides an electrical travel of 244° with essentially infinite resolution, a maximum end resistance of 2 ohms, and dielectric strength of 900 Vrms, ensuring reliable performance in demanding applications. With an operating temperature range of -55°C to +125°C, low starting torque of 3 oz-in., and robust environmental sealing with Fluorinert, this trimmer is well-suited for instrumentation, calibration circuits, and precision electronic equipment requiring stable, adjustable resistance.
