INTRODUCTION
The 303143 (0.150" lead spacing) and 303143L (0.200"
lead spacing) Bulk Metal
®
Z-Foil resistors represent the 3
rd
in a series of ultra-precision resistors since the first Bulk
Metal Foil resistor was introduced by Vishay in 1962. Each
represents an improvement on the earlier model. The TCR
slope of the 303143 and 303143L is 0.2 ppm/C (- 55 °C to
+ 125 °C, + 25 °C ref.) and is an order of magnitude better
than the original S102C. The Bulk Metal Z-Foil resistor is the
ultimate choice in the most demanding analog applications.
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.
Our application engineering department is available to
advise and to make recommendations.
