INTRODUCTION

Bulk Metal® Foil (BMF) Technology out-performs all other

resistor technologies available today for applications that

require high precision and high stability.

This technology has been invented, patented and pioneered

by Vishay. Products based on this technology are the most

suitable for a wide range of applications.

BMF technology allows to produce 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 thermal EMF, low

current noise and low voltage coefficient, all in the same

resistor.

The VSM has a full wrap around 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

A low profile solder fillet is

recommended to avoid unnecessary

stresses along top edge of

metallization. IR and vapor phase

reflow are best. Avoid the use of

cleaning agents which could attack

epoxy resins, which form part of the

resistor construction.
