DSMZ Series Voltage Divider


DSMZ ultra-high-precision, Z-Foil surface-mount voltage divider from Vishay Foil


Vishay Foil Resistors' DSMZ Series Voltage Divider Vishay Foil Resistors announced the DSMZ ultra-high-precision Z-Foil surface-mount voltage divider, which features TCR of ±0.05 ppm/°C from 0°C to +60°C and ±0.2 ppm/°C from −55°C to +125°C, PCR tracking (“ΔR due to self-heating“) of 5 ppm at rated power, tolerance match of ±0.01%, and load life stability of ±0.005%.

The DSMZ voltage divider is built on Vishay’s breakthrough “Z-based“ foil technology, which outperforms all other resistor technologies available today for applications that require ultra-high precision and stability. Greatly reducing the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR), Z-Foil improves stability by an order of magnitude compared to any other resistor technology, allowing designers to guarantee a high degree of accuracy in fixed-resistor applications.

The DSMZ voltage divider provides a matched pair of Bulk Metal® Z-Foil resistors in a single, surface-mount package with dimensions of 4.06 mm by 2.69 mm and a height profile of 1.60 mm. Device features include a load-life stability of ±0.005% for 2000 hours at 70°C; a resistance range of 100 Ω to 10 kΩ per resistor; a power rating of 0.05 W per resistor at 70°C; current noise less than -40 dB; and can withstand electrostatic discharges (ESD) of 25,000 V. The DSMZ offers a fast rise time of 1 to 10 ns (depending on resistance values) without ringing and features a non-inductive, non-hot-spot design. Datasheet
