Z201 (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Resistor with TCR of 0.05 ppm/C, PCR of 5 ppm at Rated Power, Tolerance of 0.005 % and Load Life Stability of 0.005 % FEATURES INTRODUCTION IM PR O VE D The Z201 (0.150" lead spacing) and Z201L (0.200" lead spacing) Bulk Metal(R) Z-Foil resistors represent an industry breakthrough. This is the 3rd in a series of ultra-precision resistors since the first Bulk Metal(R) Foil resistor was introduced by in 1962. Each represents an improvement on the earlier model. The TCR slope of the Z201 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(R) 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. For non-standard technical requirements and special applications, please contact us.

Improved performance (meaning increased time stability with load and other stresses) is available through factory conducted "Improved Performance Testing". The test routine is usually tailored to the user's stability objectives. A screened product can be brought down to a potential load life drift of less than 50 ppm. For example, the datasheet "7 Technical Reasons to Specify BMF Resistive Components" shows the drift characteristics of a standard product. Various screen test routines are available and all anticipated stresses must be taken into account before settling on one specific test routine. Our applications engineering department is available to discuss and recommend appropriate routines given the full spectrum of anticipated stresses and stability requirements.
