VSMP Series is the industry’s first device to provide high rated power and excellent load life stability along with extremely low TCR — all in one resistor.

One of the most important parameters influencing stability is the Temperature Coefficient of Resistance (TCR). Although the TCR of foil resistors is considered extremely low, this characteristic has been further refined over the years. The VSMP Series utilizes ultra high precision Bulk Metal® Z-Foil. The Z-Foil technology provides a significant reduction of the resistive element’s sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (Power Coefficient of Resistance, or PCR). Along with the inherently low PCR and TCR, Z-Foil technology also provides remarkably improved load life stability, low noise and tight tolerances.

The VSMP resistor has a full wraparound termination which assures secure contact during the manufacturing process, as well as providing stability during multiple thermal cyclings.

The Foil Resistors' (VFR) application engineering department is available to advise and make recommendations. For non-standard technical requirements and special applications.

• Temperature coefficient of resistance (TCR):
  • 0.05 ppm/°C typical (0 °C to + 60 °C)
  • 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)
