Most low value current sense resistors produce stray voltages due to the Seebeck effect. These stray voltages or thermal EMF can cause errors in low level measurement circuits.
Only the VPG Foil Resistors’ CSMF precision current sense resistor produces zero thermal EMF due to its superior design and utilization of Bulk Metal Foil® technology. VPG Foil Resistors’ Bulk Metal Foil® CSMF precision current sense resistor produces zero thermal EMF compared to current sense resistors of other technologies.
