3266W-1-504 is a 1/4" square multiturn cermet trimming potentiometer designed for precision resistance adjustment in industrial applications. It features a 500 kO resistance value with ±10% tolerance, 12 turns of effective travel for fine adjustability, and a sealed construction that allows thorough PC board washing. The potentiometer operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C and offers a power rating of 0.25 watt at 70°C. With its infinite resolution, low contact resistance variation, and UL 94V-0 flammability rating, this component is ideal for calibration, tuning, and adjustment circuits in instrumentation and control systems.
