The 23AR10KLFTR is a 4mm square sealed single-turn surface mount cermet trimming potentiometer designed for precision resistance adjustment in compact applications. It features a 10kO nominal resistance value with ±20% tolerance, a maximum input voltage of 200 Vdc or rms, and a power rating of 0.25 watts at 70°C. The device offers essentially infinite resolution with an actual electrical travel of 210°, dielectric strength of 500 Vrms, and insulation resistance of 100 megohms minimum. Environmental sealing with 85°C Fluorinert ensures no leaks, and the unit operates reliably across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C. This potentiometer is ideal for circuit calibration, signal conditioning, and precision tuning applications where space constraints and environmental protection are critical requirements.
