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
®
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). 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
