The 68WR500 is a 3/8" square multiturn cermet trimming potentiometer designed for precision resistance adjustment applications. It features a 20-turn nominal electrical travel with a resistance range of 10 Ohms to 2 Megohms and a standard tolerance of ±10% (±20% for values below 100 Ohms). The device is sealed with 85°C Fluorinert for environmental protection and operates reliably across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C (±250 ppm/°C for values below 100 Ohms). With a maximum power rating of 0.5 Watts at 85°C, maximum input voltage of 200 Vdc, and maximum slider current of 100 mA, the 68WR500 is well-suited for instrumentation, calibration circuits, and precision control applications where stable, fine-tuned resistance adjustment is required.
