Type 6300B 4-Terminal AC Resistance

Type 6300B 4-Terminal AC Resistance

6300B was designed under the technical guidance of NMIJ/AIST (The National Metrology Institute of Japan/The National Institute of Advanced Industrial Science and Technology/). The precision AC standard resistor realized AC-DC error less than 10 ppm at under 10 kHz and phase angle error less than 50μrad. The resistance is extremely stable thus it can be used as a resistance standard for DC as well as AC.


  • Excellent frequency response and minimal phase angle error
  • Selectable either BPO/MUSA or BNC connector
  • Suitable for 4-Terminal LCR Meter calibration due to 4-Terminal structure
  • Resistance elements are thermally processed full well, so 6300B has a small temperature coefficient and high stability
  • Best suited for calibration standard because of excellent accuracy, temperature coefficient and aging
  • Variety of resistance values are available, so it can be used for many applications including temperature measurement.
