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.
Non hot spot design
Terminal finishes available:
lead (Pb)-free
tin/lead alloy

•
Matched sets are available per request
Any value available within resistance range (e.g. 1K2345)
Prototype samples available from 72 h. For more
information, please contact foil@vishay.com
For better performances please review Z2ꢀꢁ and Sꢁꢀ2C
Series datasheets
The BMF provides an inherently low and predictable
Temperature Coefficient of Resistance (TCR) and excellent
load life stability for high precision analog applications.
•
Model VSH 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.
