The 84PR20LFTR is a multi-turn trimmer potentiometer from BI Technologies' Model 84 series, designed for precision resistance adjustment in surface-mount applications. It features a 1/4" square cermet element with 12 turns of electrical travel, offering essentially infinite resolution and a resistance range from 10 Ohms to 2 Megohms with ±10% tolerance. The device is rated for 0.25 watts at 85°C, with a maximum input voltage of 200 Vdc or rms, maximum slider current of 100 mA, and dielectric strength of 900 Vrms. It operates reliably across -65°C to +150°C with excellent environmental stability, including moisture resistance and thermal shock performance. This trimmer is ideal for calibration and fine-tuning applications in instrumentation, data acquisition systems, and precision electronic circuits where compact size and reliable adjustment are required.
