The 68PR5KLF 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 and a standard tolerance of ±10% (±20% for values below 100 Ohms). The device is sealed with 85°C Fluorinert for protection against moisture and environmental contaminants, with an operating temperature range of -55°C to +125°C and a temperature coefficient of ±100 ppm/°C (±250 ppm/°C for values 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 features essentially infinite resolution, mechanical stops with clutch action at both ends, and is commonly used in instrumentation, calibration circuits, and precision control applications where reliable, long-term performance is required.
