The VPG Foil Resistors product group of Vishay Precision Group announced its Powertron PCS Series power current sensors that combine high-precision resistors with both high power and a low temperature coefficient of resistance (TCR).
These power current sensors, employing proprietary Bulk Metal Foil® technology, deliver high-precision measurements without the need for compensation for external temperature effects. Units are offered in 73 unique standard packages, with resistance ranges from 1 mOhm to 10 Ohms, a TCR down to 3 ppm, and load stability and resistance tolerances to ±0.01%. They are lead free and RoHS compliant.
To meet 30 Watt power requirements, the PCS Series power current sensors can be mounted to an external heat sink. This allows them to provide increased rated power.
Depending upon selected model, individual resistor networks may be reconfigured prior to shipment, at customer request. High-precision Powertron resistors feature multiple metal foil grade options, including CuMnSN, CuNiMn and NiCr, which are integrated along with VPG’s own patented Bulk Metal Foil technology to create high-reliability finished product designs.
