INTRODUCTION
Vishay Foil Resistors’ new VSMF model is targeted for
applications that are prone to high thermal stress or
mechanical stress; it features low TCR, excellent load life
stability, tight tolerance, excellent shelf-life stability, low
current noise, high speed, and low voltage coefficient—all
in the same resistor.
It is well known that chips of 1206 dimensions and
larger can occasionally develop cracks and even fall off
the printed circuit board, especially when exposed to
temperature cycling. These instances are due to stress-
inducing mishandling of the PC board (e.g., bending during
assembly), excess thermal gradients, or thermal shock.
The latter two can be divided into two categories:
1. Thermal stress induced by changes in ambient
temperature. Here, different coefficients of expansion
induce mechanical stress as PCB compression
imposes tension on the resistor (or vice versa).
2. Thermal stress caused by internal heat generation
(load). Here, power dissipation within the resistor
generates temperature differentials between the
resistor and the PCB, resulting in variable stresses.

•ꢀTerminalꢀfinish:ꢀleadꢀ(Pb)-freeꢀorꢀtin/leadꢀalloy*
Note:
Stress cycling due to these two phenomena causes
material fatigue and cracks.
*
Pb containing terminations are not RoHS compliant,
exemptions may apply.
Vishay Foil Resistors’ new VSMF series of surface-mount
chip resistors feature flexible terminations to prevent
cracking of the body of the chip or delamination from the
board, especially in resistors with high length-to-width
aspect ratios.

RESISTANCE VALUE(1)
(-––/C to ꢂ12–/C, ꢂ2–/C Ref.)
For applications with high thermal stresses, designers
typically use molded resistors with flexible terminations.
These are larger than chip resistors and require more real
estate on the PCB. Vishay Foil Resistors has developed
and patented a solution which permits direct replacement
of standard chips by chips with flexible terminations.

* To acquire a precision resistance value, the Bulk Metal® Foil
chip is trimmed by selectively removing built-in “shorting bars.”
To increase the resistance in known increments, marked areas
are cut, producing progressively smaller increases in resistance.
This method eliminates “hot spots” and improves the long term
stability of the resistor.
