INTRODUCTION
The Bulk Metal
®
Foil (BMF) technology out-performs all
other resistor technologies available today for applications
that require high precision and high stability, and allows
production of customer oriented products designed to
satisfy challenging and specific technical requirements.
The BMF provides an low and predictable Temperature
Coefficient of Resistance (TCR) and excellent load life
stability for high precision applications.
The RB Series also offers excellent load life stability, tight
tolerance, low current noise, and low voltage coefficient,
all in the same resistor.
The flip chip configuration provides a substantial PCB
space saving of more than 35% vs. a surface-mount chip
with wraparound terminations. The RB Series is available
in any value within the specified resistance range.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
