The UR73 Current Sensing Chip Resistor offers very low resistance with a range of 30m Ohms to 100m Ohms. It utilizes advanced thick film technology and offers low T.C.R. from 𫏌ppm to 𫑢ppm, indicative of high precision resistors. The UR73 is available in two sizesרA (2.0 x 1.25 mm) and 2B (3.2 x 1.6 mm), both have a power rating of 0.25W, and are lead free with tolerance of ۫% and ۯ%. These resistors have an operating temperature range from -55°C to +125°C, and are suitable for reflow and flow soldering.
