Ultra High Precision Foil Wraparound Surface Mount Chip Resistor

INTRODUCTION

VSMP Series is the industry’s first device to provide High

Rated power, 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

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). Along with the inherently low PCR and

TCR, Z-Foil technology also provides remarkably improved

load life stability, low noise and availability of tight tolerance.

The VSMP has a full wraparound termination which ensures

safe handling during the manufacturing process, as well as

providing stability during multiple thermal cyclings.

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
