INTRODUCTION

The 303143 (0.150" lead spacing) and 303143L (0.200"

lead spacing) Bulk Metal

Z-Foil resistors represent the 3

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.
