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
