VPR220SZ (Z-Foil)

Vishay Foil Resistors

Model VPR220SZ, made from Vishay Bulk Metal

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
