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

Our Applications Engineering Department is available to

advise and to make recommendations for non standard

technical requirements and special applications, please
