INTRODUCTION

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 inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.

Model VSM offers low TCR, excellent load life stability, tight
tolerance, excellent shelf life stability, low current noise and
low voltage coefficient, all in the same resistor.

The VSM has a full wraparound termination which ensures
safe handling during the manufacturing process, as well as
providing stability during multiple thermal cyclings.

Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
