INTRODUCTION
Bulk Metal
®
Z-Foil technology out-performs all other resistor
technologies available today for applications that require
ultra-high precision and ultra-high stability. The Z-Foil
technology provides a significant reduction of the resistive
element’s sensitivity to ambient temperature variations
(TCR) and to self heating when power is applied (power
coefficient).
Model VFB1515N offers low TCR (both absolute and
tracking), low PCR (both absolute and tracking), excellent
load life stability, tight tolerance, excellent ratio stability, and
low current noise, all in one package. 0.05 ppm/°C absolute
TCR removes errors due to temperature gradients.
The VFB1515N ball grid array (BGA) surface mount
3-resistor network provides tight tolerance matching and
TCR tracking between 3 resistors simultaneously etched on
one piece of foil on a common substrate. The electrical
specifications of this integrated construction offers improved
performances and better real estate utilization over discrete
resistors and matched pairs.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
