Any value available within resistance range
The Z-foil technology provides a significant reduction of the
resistive component´s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
Designers can now guarantee a high degree of stability and
accuracy in fixed-resistor applications using solutions based
on Vishay´s revolutionary Z-foil technology.
The E102Z (0.150" lead spacing) and E102JZ (0.200" lead
spacing) extends the range of the ultra high precision Z201
and Z201L.
Our application engineering department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
