Product Details

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.
