VPG Foil Resistors

RWA, RWB, and RWC Precision SMD Resistors

VPG Foil Resistors SMD resistors are precision components built using Bulk Metal® foil technology

Image of VPG Foil Resistors RWA, RWB, and RWC Precision SMD ResistorsVPG Foil Resistors RWA, RWB, and RWC series resistors are precision surface-mount components built using Bulk Metal foil technology for high stability and low temperature coefficient of resistance (TCR). Available in 0603, 0805, and 1206 package sizes, respectively, these resistors are designed for demanding applications requiring consistent performance under thermal and electrical stress.

The series supports temperature coefficients as low as 0±2 ppm/°C and resistance tolerances down to ±0.01%, with typical load life stability of ±0.005% at +70°C over 2,000 hours at rated power. With resistance ranges from 5 Ω to 30 kΩ depending on type, these resistors are qualified to AEC-Q200 standards and built for precision circuits in industrial, automotive, and instrumentation applications.

All three types are constructed with high-purity alumina ceramic substrates and offer no standard E-series values, allowing for custom resistance values such as 1 k 234 Ω.
