Low value flat chip current-sense resistor uses thick-film technology in a 2512 surface-mount package. The 20 mΩ resistance value falls in the LRF flip-chip orientation range for values up to 25 mΩ. The device is rated for 2 W at 70 °C and derates to zero power at 150 °C. Wraparound terminations use an electroplated nickel barrier with matte tin or tin-lead finish options. The LR(F)2512 family is AEC-Q200 qualified and supplied in plastic tape-and-reel packaging.
