Resistors NPI: LRMAP2726 Low Resistance Metal Alloy Power Resistor

24 June 2022

LRMAP2726 – Low Resistance Metal Alloy Power Resistors

0.2 to 5mΩ – 4-Terminal Kelvin – Accurate current sense, LRMAP2726 is a high power, low value SMT shunt resistor. With values down to 200µΩ and a power rating of 5W, the theoretical maximum measurable current is up to 158A, so in effect it is restricted only by the current carrying capacity of the PCB tracks. With 1% tolerance and down to 25ppm/°C, this product combines good precision with the high surge capacity of metal alloy technology.

Features

  • 5W rating at 70°C
  • Values 0.2 to 5mΩ
  • 4-terminal Kelvin J-lead terminations
  • Robust welded construction
  • TCR down to 25ppm/°C
  • Hotspot distanced from PCB
  • Low inductance

Benefits

  • Spacing from PCB minimises the board temperature rise and enhances reliability of the assembly
  • 4-terminal Kelvin connections improve precision meaning that a small part of the designer’s error budget is consumed, enabling more design freedom elsewhere in the circuit

Ideal Applications

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