INTRODUCTION
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 Bulk Metal® Foil is considered
extremely low, this characteristic has been further
refined over the years. The VSMP Series utilizes ultra
high precision 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.
