1 / 4 page Document Number: 63064 For any questions, contact: foil@vishay.com www.vishay.com Revision: 22-Sep-08 1 VPR220Z (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Power Resistor in TO-220 Configuration with TCR of ± 0.05 ppm/°C, Tolerance to ± 0.01 % and Power Rating to 8 W Vishay Foil Resistors manufacture any resistance value within the given resistance range (e.g. 10 Ω or 10.1234 Ω) without influencing cost or lead time Model VPR220Z, made from Vishay Bulk Metal® Z-foil, offers very low TCR, high stability, tight tolerance, low PCR and fast response time in a small molded resistor. The Z-foil technology provides a significant reduction of the resistive components sensitivity 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.
