SMNZ (Z-Foil) Series Resistor Network

Vishay Precision Group SMNZ Z-Foil Resistors integrate four matched Z-Foil resistors into a single package for applications where resistor-to-resistor tracking is critical. The devices are designed for bridge circuits, instrumentation amplifiers, DAC ladders, and summing networks that require resistor ratios to remain stable through temperature variations, self-heating effects, and long-term operation. By placing all four resistors in a shared thermal environment, the SMNZ resistor networks help maintain precise ratio-matching and tracking performance. In many precision measurement and signal-conditioning circuits, resistor tracking can have a greater impact on overall accuracy than absolute resistance value. Vishay Precision Group SMNZ Z-Foil Resistors provide network-level specifications for TCR tracking, ratio stability, power-coefficient tracking, and tolerance matching.
