描述

The RJR24FW201M is a sealed multiturn cermet trimming potentiometer (trimpot) with a 3/8" square form factor designed for precision voltage and resistance adjustment in industrial applications. It features a nominal resistance of 200 ohms with ±10% tolerance, infinite resolution, and an effective travel of 25 turns, delivering voltage adjustability of ±0.01% and resistance adjustability of ±0.05%. The device is rated for 0.5 watt at 85 °C (maximum 300 volts), with an insulation resistance of 1,000 megohms minimum at 500 VDC and a dielectric strength of 1,000 VAC at sea level. Operating across -55 °C to +150 °C with a temperature coefficient of ±100 ppm/°C, it withstands 20 g vibration and 100 g shock, and is qualified to MIL-PRF-39035 high-reliability standards with a 0.01% failure rate. Common applications include precision calibration, signal conditioning, and tuning circuits in aerospace, military, and industrial control systems.
