Z202
Any value at any tolerance available with resistance range
The Z202 is a miniaturized version of the now famous Z201. It is
made with a Bulk Metal
®
Z-Foil element so it retains all of the
inherent performance of Z-Foil resistors.
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.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
