303143, 303143L (Z-Foil) Vishay Foil Resistors Models 303143 and 303143L (Ultra High Precision Fixed Resistor Z-Foil Z201), Screen/Test Flow as modified from S-311-P813 Proposed by NASA FEATURES Temperature coefficient of resistance (TCR): 0.05 ppm/C typical (0 C to + 60 C) 0.2 ppm/C typical (- 55 C to + 125 C, + 25 C ref.) Power coefficient of resistance "R due to self heating": 5 ppm at rated power Rated power: 0.6 W at 70 C 0.3 W at 125 C Resistance tolerance: to 0.005 % Load life stability: to 0.005 % at 70 C, 2000 h at rated power INTRODUCTION Resistance range: 10 to 100 k The 303143 (0.150" lead spacing) and 303143L (0.200" lead spacing) Bulk Metal(R) 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. Electrostatic discharge (ESD) up to 25 000 V 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 Non-inductive, non-capacitive design Rise time: 1.0 ns effectively no ringing Current noise: 0.010 VRMS/V of applied voltage (< - 40 dB) Thermal EMF: 0.1 V/C max. 0.05 V/C typical Voltage coefficient: < 0.1 ppm/V Non-inductive: 0.08 H Terminal finish: tin/lead alloy Maximum working voltage: 245 V Drop in replacement for S102C/K Matched sets are available per request For prototype units, append a "U" to the model number (example: 303143U). These units include only the 100 % screening requirements (table 4, page 4). For more information, please contact foil@vishaypg.com advise and to make recommendations. TABLE 1 - TOLERANCE AND TCR VS.
