The 84PR20KLF is a Model 84 multiturn cermet trimming potentiometer designed for precision adjustment applications in surface-mount configurations. It features a 1/4" square form factor with 12 turns of nominal electrical travel, supporting resistance values from 10 ohms to 1 megohm with ±10% tolerance. The device operates at a maximum input voltage of 200 Vdc or rms, with a power rating of 0.25 watts at 85°C, maximum slider current of 100 mA, and dielectric strength of 900 Vrms. Environmental specifications include an operating temperature range of -65°C to +150°C, temperature coefficient of ±100 ppm/°C (±250 ppm/°C for resistances =100 ohms), and insulation resistance minimum of 1,000 megohms. This potentiometer is ideal for precision calibration, signal conditioning, and tuning applications in industrial instrumentation, medical devices, and electronic test equipment where reliable multiturn adjustment and environmental stability are required.
