Revision: 26-Mar-10 1
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
