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 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.
