1.5 W molded current sense resistors come in 2512 size

KOA SPEER SLW1 a 1.5 Watt, 2512 size molded current sensing resistor provides resistance values ranging from 3mΩ up to 100mΩ in several tolerances as low as 0.5% with a wide operating temperature range of -55°C to +180°C. Chip’s special electrode shape easily absorbs thermal expansion and shrinkage stress. Suitable for reflow, wave, and iron soldering, devices are made with flame retardant molded construction providing high mechanical stability. http://www.koaspeer.com
