The Z-foil technology provides a significant reduction of the resistive components sensitiv ity to ambient temperature variations and applied power changes. Designers now can 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 make recommendations. For non-standard technical requirements and special applications, please contact us.
