, please see information on our precision current shunts.
| Model Number | Nominal Resistance | Tolerance in ppm | Rated Current | Temperature Coefficients |
| 2000 | 1 Ohm | <5 | 1 Amp | < 2 ppm / °C |
| 2001 | 0.1 | <5 | 3 | |
| 2002 | 0.01 | <15 | 10 | |
| 2003 | 0.001 | <20 | 30 | < 15 ppm / °C |
| 2004 | 0.000 1 | <50 | 100 | |
| 2005 | 0.000 01 | <100 | 300 | |
| Special Values available on request – use the following format | ||||
| Specify 20(X)(Y) | 20 = 2000 Series | X = Resistance Y = Range | 2051 = 0.5 2023 = 0.002 |
Notes
- Initial 12 month stability < 10 ppm
- Tolerance is accuracy at time of manufacture
- Temperature coefficients are at nominal 25°C +/-5°C.
