INTRODUCTION  
Bulk Metal® Foil Technology out performs all other resistor  
technologies available today for applications that require  
high precision and high stability.  
This technology has been pioneered and developed by  
VISHAY, and products based on this technology are the  
most suitable for a wide range of applications.  
Generally Bulk Metal® Foil technology allows us to produce  
customer orientated products designed to satisfy challenging  
and specific technical requirements.  
Matched Sets Available  
Terminal Finishes Available: Lead (Pb)-free  
Tin/Lead Alloy  
Any value available within resistance range (e.g. 1K234)  
The VSR series of resistors is a low cost version of the well  
established S-Series of resistors. These resistors are made  
of foil elements so all of the inherent performance of foil is  
retained. They do not however, have the same TCR or  
tolerance ranges (see table 1 for details). These products  
find a wide range of usage in high end stereo equipment and  
some grades of test and measurement equipment.  
Prototype samples available from 48 hours. For more  
information, please contact foil@vishay.com  
For better performances please review the S Series  
datasheet  
Note  
1. For values below 50 Ω please contact Application Engineering  
Standoffs are dimensioned to provide a minimum lead  
clearance of 0.010 inches between the resistor body and the  
printed circuit board, when the standoffs are seated on the  
board. This allows for proper cleaning after the soldering  
process.  
APPLICATIONS  
Industrial  
Medical  
Audio (high end stereo equipment)  
Test and Measurement equipment  
Precision Amplifiers
