The 84WR200KLFTR is a Model 84 multiturn cermet trimming potentiometer featuring a 1/4" square surface mount design for compact PCB integration. It offers a resistance range of 10 Ohms to 1 Megohm with ±10% tolerance, 12 turns of electrical travel, and a maximum input voltage of 200 Vdc or rms. The device is rated for 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. Operating across -65°C to +150°C with a temperature coefficient of ±100 ppm/°C (±250 ppm/°C for resistances =100 Ohms), it provides excellent environmental stability including resistance to thermal shock, moisture, vibration (20G's, 10 to 2,000 Hz), and mechanical shock (100G's). This potentiometer is ideal for precision calibration and adjustment applications in instrumentation, industrial control systems, and consumer electronics requiring reliable, long-term performance in demanding environments.
