INTRODUCTION
Bulk Metal® Foil (BMF) Technology out-performs all other
resistor technologies available today for applications that
require high precision and high stability.
This technology has been invented, patented and pioneered
by Vishay. Products based on this technology are the most
suitable for a wide range of applications.
