The 68WR20LF is a 3/8" square multiturn cermet trimming potentiometer designed for precision resistance adjustment applications. It features 20 turns of nominal electrical travel with a resistance range of 10 Ohms to 2 Megohms, standard resistance tolerance of ±10% (±20% for values below 100 Ohms), and essentially infinite resolution. The device is sealed with 85°C Fluorinert for protection against leaks and operates reliably across a wide temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C (±250 ppm/°C for resistances below 100 Ohms). It supports a maximum input voltage of 200 Vdc and a maximum slider current of 100 mA, with a power rating of 0.5 Watts at 85°C. The potentiometer is commonly used in instrumentation, calibration circuits, and precision control applications where fine adjustment and long-term stability are required.
