RJR26FX203P is a 1/4" multiturn cermet trimming potentiometer (Trimpot) designed for precision adjustment applications in industrial environments. It features a 20 kO nominal resistance value with ±10% tolerance, infinite resolution, and sealed construction rated for MIL-PRF-39035 high-reliability applications. The device operates over a temperature range of -65°C to +150°C with a temperature coefficient of ±100 ppm/°C, and delivers 0.25 watts at 85°C under 200 volts maximum. With 12 turns of effective travel, voltage adjustability of ±0.02%, and resistance adjustability of ±0.05%, this potentiometer provides exceptional precision for circuit tuning and calibration. Its robust design includes 10,000-hour load life at 85°C, 100 G shock resistance, and 20 G vibration tolerance, making it ideal for aerospace, military, telecommunications, and medical instrumentation applications requiring sealed, high-reliability trimming solutions.
