A40B Series Precision DC and AC Current Shunts

The A40B shunt set consists of 14 low-inductance coaxial current shunts, adapters, and connectors. Designed for currents from 1 mA to 100A, the shunts are for laboratory use in making directly measured absolute ac or dc current measurements as well as ac/dc current transfer measurements. Ideal for traditional precision current applications, verification of high current transconductance amplifiers, and measurement of non-sinusoidal wave shapes.


  • Usable from dc to 100 kHz
  • 14 individual dc and ac current shunts with a 1, 2, 5 sequence
    over 6 decades of current
  • Stability typically better then ± 5.0 µΩ/Ω for one year
  • Typical angular accuracy of better than ± 0.003º at 1 kHz
