LRMAP2817 – Low Resistance Metal Alloy Power Resistors

21 September 2021

1 to 100mΩ – Compact Footprint – Accurate Current Sense. LRMAP2817 is a high power, SMT shunt resistor. With values down to 1mΩ and a power rating on FR4 of 5W, the maximum measurable current is 71A, and in most cases restricted only by the capacity of the PCB tracks.

With 0.5% tolerance and 50ppm/°C TCR, this combines good precision with the high surge capacity of metal alloy technology in a compact 2817 footprint.


  • 5W rating at 70°C on FR4
  • Values 1 to 100mΩ
  • Compact 7.1 x 4.3mm footprint
  • Tolerance down to 0.5%
  • TCR down to 50ppm/°C


  • Low thermal impedance minimises the temperature rise and enhances reliability of the assembly.
  • High surge tolerance gives reliable product performance under inrush and momentary short circuit conditions.

Ideal Applications

  • Power supply
  • Motor drive
  • Battery monitoring
  • Solar cell monitoring
  • Process control
