VPR220SZ (Z-Foil)
Vishay Foil Resistors
Ultra High Precision Z-Foil Surface Mount Power Resistors in
TO-220 Configuration with TCR of ± 0.05 ppm/°C,
Tolerance to ± 0.01 % and Power Rating to 8 W
Any value at any tolerance available within resistance range
Model VPR220SZ, made from Vishay Bulk Metal® Z-Foil,
offers very low TCR, high stability, tight tolerance, low PCR
and fast response time in a small surface mount 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
