The RJR26FW104P is a 1/4-inch sealed multiturn trimming potentiometer (Trimpot) manufactured by Bourns for high-reliability industrial applications. It features a 100 kO resistance value with a ±100 ppm/°C temperature coefficient, cermet element construction, and is qualified to MIL-PRF-39035 with a 0.1% failure rate designation. The device operates across -65 °C to +150 °C, delivers 0.25 W at 85 °C (maximum 200 V), and provides 12 turns of effective travel with infinite resolution and ±0.05% resistance adjustability. It exhibits 1,000 MO minimum insulation resistance at 500 VDC, 600 VDC dielectric strength at sea level, and withstands 20 g vibration and 100 g shock with mechanical stops and a 3.0 oz-in maximum adjustment torque. This potentiometer is ideal for precision calibration, signal conditioning, and tuning applications in aerospace, military, and industrial control systems where reliability and environmental stability are critical.
