The RJ26FW201 is a sealed multiturn cermet trimming potentiometer (Trimpot) designed for precision resistance adjustment in industrial and military applications. It features a standard resistance range from 10 ohms to 1 megohm with ±10% tolerance, infinite resolution, and exceptional adjustability of ±0.02% for voltage and ±0.05% for resistance. The device is rated for 0.25 watt at 85 °C (maximum 200 volts), operates across -65 °C to +150 °C with a temperature coefficient of ±100 PPM/°C, and provides 1000 megohms minimum insulation resistance with 600 VAC dielectric strength at sea level. It withstands 20 g vibration and 100 g shock with 12 turns of effective travel and is qualified to MIL-PRF-22097 and MIL-PRF-39035 standards. This sealed design is ideal for circuit calibration, gain adjustment, and offset trimming in aerospace, defense, and industrial instrumentation where reliability and precision are critical.
