New foil resistors offer industry reliability and long-term stability

The VPG Foil Resistors has launched the Powertron PCS Series, a high-reliability power current sensor family, offering exceptional long-term stability, reliability and performance. Design of the series incorporates the company’s own proprietary bulk metal foil technology, combining high-precision resistors with both high power and a low temperature coefficient of resistance (TCR). The result is a power current sensor which offers truly industry-exclusive, high-precision measurements, without the need for compensation for external temperature effects. Units are offered in 73 unique standard packages, with resistance ranges from 1mOhm to 10Ohms, a TCR down to 3ppm, and load stability and resistance tolerances to ±0.01%. They are lead free and RoHS compliant. To meet 30 Watt power requirements, the series may be further mounted to an external heat sink. This allows them to provide three times more rated power than any other comparable industry model.
