Powertron PCS Series Offers Industry-Exclusive Reliability

The VPG Foil Resistors product group of Vishay Precision Group, manufacturers of the industry’s most precise and stable Bulk Metal Foil resistors, have announced the global market launch of the Powertron PCS series, a high-reliability power current sensor family, offering exceptional long-term stability, reliability and performance.

Design of the Powertron PCS series incorporates VPG’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 1 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 30W power requirements, the PCS 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.

The Powertron brand of VPG Foil Resistors specializes in the design and manufacture of reliable high-precision resistors and power current sensors. Hundreds of standard model configurations are derived from one of the industry’s most extensive portfolios of customer-selectable housings, materials, substrates, and metal foil grade combinations. 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. For high-power applications, VPG designs and manufactures its own Powertron thick-film chips, featuring less demanding load stability, TCR and resistance tolerances. Custom packages, configurations, parameters, and specifications may be further produced in OEM volumes with competitive lead times. Please consult the factory for details.
