Low Resistance Current Sensing (Through Hole)

IRHF series precision shunt 50A - 500A

IRHF series precision shunt 50A - 500A

With a temperature coefficient of ± 15ppm/°C between +20°C and +60°C, self heating errors are kept to a minimum. Custom current or output voltages are also available.

  • 50 - 500A
  • 100mV output
  • 1% - 0.1% tolerance
  • Custom design options
All models supply 100mV at full current rating. The voltage output is available via a Kelvin connected flying lead, which enables a resistance tolerance of between 0.1% and 1%.
