INTRODUCTION
The Z-foil technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
Designers can now guarantee a high degree of stability and
accuracy in fixed-resistor applications using solutions
based on Vishay‘s revolutionary Z-foil technology.
Model VCS1625Z is a surface mount chip resistor designed
with 4 pads for Kelvin connection. Utilizing Vishay’s Bulk
Metal
®
Z-foil as the resistance element, it provides
performance capabilities far greater than other resistor
technologies can supply in a product of comparable size.
0.05 ppm/°C absolute TCR removes errors due to
temperature gradients.
This small device dissipates heat almost entirely through the
pads so surface mount users are encouraged to be generous
with the board’s pads and traces.
Our application engineering department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.
