The 84WR1KLFTR is a multi-turn trimmer potentiometer from BI Technologies designed for precision resistance adjustment in electronic circuits. It features a cermet resistive element with a 1/4" square top adjustment and surface-mount configuration, offering a resistance range of 10 Ohms to 2 Megohms with ±10% tolerance. The device provides 12 turns of electrical travel with essentially infinite resolution and supports a maximum input voltage of 200 Vdc or rms, with a power rating of 0.25 watts at 85°C. With a maximum slider current of 100 mA, dielectric strength of 900 Vrms, and insulation resistance of 1,000 Megohms minimum, this trimmer is well-suited for calibration and fine-tuning applications in instrumentation, telecommunications, and consumer electronics where reliable, adjustable resistance is required.
