Vishay Releases VFB1012D, VFB1515N and VFB2028N, Three New Ultra-High-Precision Bulk Metal Z-Foil Surface-Mount Resistor Networks
The new ultra-high-precision Bulk Metal® Z-Foil surface-mount resistor networks (VFB1012D, VFB1515N and VFB2028N) offer the best combination of stability features ever achieved in the ball grid array (BGA) format. The devices provide 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., PCR tracking (“?R due to self heating”) of ± 5 ppm at rated power, and a load life stability ratio of ± 0.01 % (100 ppm) for 2000 hours at + 70 °C. The devices outperform all other resistor technologies available today for applications that require ultra-high precision and stability by providing a significant reduction of the resistive component’s sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). The BGA devices provide tight tolerance matching of ± 0.01 % and TCR tracking of 0.1 ppm/°C between multiple resistors simultaneously etched on one piece of Foil on a common substrate…
