INTRODUCTION
VCS232Z is the industry’s first device to prove high rated
power, excellent load life stability along with low TCR and all
in one resistor.
• Load Life stability: < 0.005% 2W at 25°C for 2000 hours
• Power rating @ + 25°C: 2 Watts
The New Z-Foil Technology provides a significant reduction
of the resistive components sensitivity to ambient
temperature variations (TCR) and applied power changes
(PCR).
The latest development in Foil resistors technology have
reduced the temperature coefficient of Resistance (TCR), to
below 0.2 ppm/°C (part per million per degree centigrade).
0.05 ppm/°C Absolute TCR removes error due to
temperature gradients.
By taking advantage of the overall stability and reliability of
Vishay Bulk Metal® Z-Foil resistors, designers can
significantly reduce circuit errors and greatly improve overall
circuit performances.
Model VCS232Z is a 4 lead kelvin connected device.
