The 72PR100K is a single-turn trimmer potentiometer manufactured by BI Technologies, 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 essentially infinite resolution with a nominal electrical travel of 244°, maximum end resistance of 2 ohms, and dielectric strength of 900 Vrms, ensuring reliable performance in demanding applications. Operating across a wide temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, the 72PR100K is well-suited for instrumentation, calibration circuits, and precision control applications where stable, adjustable resistance is required.
