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.
