The 64XR200KLF is a Model 64 multi-turn trimmer potentiometer manufactured by BI Technologies, featuring a 1/4" square cermet resistive element designed for precision tuning applications. It offers a standard resistance range from 10 ohms to 1 megohm with ±10% tolerance, supporting a maximum input voltage of 200Vdc or rms and a maximum slider current of 100mA, with a power rating of 0.25 watts at 85°C. The device provides 12 turns of electrical travel with essentially infinite resolution and a maximum end resistance of 2 ohms, ensuring smooth and accurate adjustment. With a dielectric strength of 900Vrms, minimum insulation resistance of 1,000 megohms, and operating temperature range of -65°C to +150°C, this trimmer is well-suited for precision calibration in instrumentation, test equipment, and industrial control systems where reliable performance and fine adjustment capability are essential.
