Vishay's New VFCD1505 Ultra-High-Precision Z-Foil Surface-Mount Flip Chip Voltage Divider Combines a Low Absolute TCR of ±0.05 ppm/°C, TCR Tracking of 0.1 ppm/°C, Load Life Stability Ratio of ±0.005 %, and PCR Tracking of 5 ppm at Rated Power

Vishay Intertechnology, Inc. (NYSE: VSH) announces the new VFCD1505 surface-mount flip chip voltage divider, which provides a low absolute TCR of ±0.05 ppm/°C from 0 °C to +60 °C and ±0.2 ppm/°C from 55 °C to +125 °C, +25 °C Ref., an excellent PCR tracking ("ΔR due to self heating") of ±5 ppm at rated power, and a load life stability ratio of ±0.005 %.

Provides tight tolerance matching of ±0.01 % (available down to ±0.005 %) and TCR tracking of 0.1 ppm/°C between two resistors simultaneously etched on one piece of foil on a common substrate

The new voltage divider is built on Vishay.s breakthrough "Z- foil" technology, which provides a significant reduction of 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 Perspective:

Built on Vishay's Z-foil technology, the new VFCD1505 surface-mount flip chip voltage divider provides a low absolute TCR of ±0.05 ppm/°C from 0 °C to +60 °C and ±0.2 ppm/°C from 55 °C to +125 °C, +25 °C Ref., and an excellent PCR tracking ("ΔR due to self heating") of ±5 ppm at rated power between two resistors simultaneously etched on one piece of foil on a common substrate. For designers, the electrical specifications of this integrated construction offer improved performances and better real estate utilization over discrete resistors and matched pairs.

Availability:

Samples and production quantities of the VFCD1505 voltage divider are available now, with lead times of 72 hours for samples, and three weeks for standard orders.
