The 3260W-1-502 is a 1/4" square Trimpot trimming potentiometer manufactured by Bourns, designed for precision adjustment applications in industrial environments. This multiturn wirewound device features a 5,000 ohm resistance value with ±5% tolerance, 0.34% nominal resolution, and an 11-turn adjustment angle for fine control. The potentiometer operates across a wide temperature range of -65°C to +150°C with a temperature coefficient of ±70 ppm/°C, and delivers 0.25 watts at 85°C. It is sealed, RoHS compliant, and listed on the QPL for MIL-R-27208 style RT26, with dielectric strength rated at 600 VAC at sea level and 1,000 megohms minimum insulation resistance. The device is ideal for circuit trimming, calibration, and processing applications where reliable, repeatable adjustment and environmental durability are required.
