DESCRIPTION

The 68WR100K is a 3/8" square multiturn cermet trimming potentiometer designed for precision voltage and current adjustment in electronic circuits. It features a 100 kO resistance value with ±10% tolerance, supports up to 200 Vdc input voltage, and handles a maximum slider current of 100 mA with a 0.5 W power rating at 85°C. The device provides 20 turns of nominal electrical travel with essentially infinite resolution and maintains excellent stability across environmental conditions, including a temperature coefficient of ±100 ppm/°C and an operating range from -55°C to +125°C. With its sealed Fluorinert construction, low end resistance of 2 O maximum, and 1,000 MO minimum insulation resistance, the 68WR100K is ideal for precision calibration, signal conditioning, and tuning applications in industrial instrumentation, audio equipment, and test equipment where reliable long-term performance and minimal drift are critical.
