The RJ12FY504 is a sealed multiturn cermet trimming potentiometer (Trimpot®) designed for precision adjustment in industrial and processing applications. It features a 1-1/4" rectangular body with solderable printed circuit pins and flexible leads (7 strands of 30 AWG), rated for 1.0 watt at 70 °C with a maximum voltage of 400 volts. The device operates across a temperature range of -55 °C to +150 °C with a temperature coefficient of ±100 ppm/°C, and meets MIL-PRF-22097 specifications for sealed industrial trimmers. It withstands 20 g vibration and 50 g shock with minimal resistance change, and is qualified for 200 rotational cycles and 1,000 hours of load life at 70 °C. The RJ12FY504 is ideal for precision tuning and calibration in sealed environments where reliability and stability are critical.
