Models 303143 And 303143L (Ultra High Precision Fixed Resistor Z-Foil Z201), Screen/Test Flow As Modified From S-311-P813 Proposed By NASA

The 303143 (0.150" lead spacing) and 303143L (0.200" lead spacing) Bulk Metal ® Z-Foil resistors represent the 3rd 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. By Vishay Intertechnology
