The 23BR20KLFTR is a single-turn sealed trimmer potentiometer designed for precision resistance adjustment in electronic circuits. It features a 4 mm square sealed design with cermet element, rated for 20 kO resistance with ±20% tolerance and 0.25 watts power rating at 70°C. The device operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C (or ±250 ppm/°C for values <200 Ohms or >1 Megohm), and provides essentially infinite resolution with 200° nominal electrical travel. Its sealed construction with 85°C Fluorinert ensures reliable performance in harsh environments, with excellent environmental resistance including thermal shock, moisture resistance, and vibration immunity. This trimmer is ideal for calibration and tuning applications in instrumentation, consumer electronics, and industrial control systems where compact size and environmental sealing are required.
