Z202 Vishay Foil Resistors Ultra High Precision Z-Foil Miniature Resistor with TCR of ± 0.05 ppm/°C, PCR of 5 ppm at Rated Power and Tolerance to ± 0.01 % FEATURES 0745 - 100R01 0.01 % V Z202 Any value at any tolerance available with resistance range The Z202 is a miniaturized version of the now famous Z201. It is made with a Bulk Metal® Z-Foil element so it retains all of the inherent performance of Z-Foil resistors. 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.
