VPR220Z Datasheet, PDF (1/4 Pages) Vishay Siliconix – 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

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
