Flexible Termination
INTRODUCTION
Flexible Terminations with Zero TCR
Vishay’s new flexible termination resistor with the second
generation of Z-Foil (Z1-Foil) features new orders of accuracy,
stability and speed in a size small enough for permanent
assembly in operational equipment.
It is well known that chips of 1206 and larger dimensions
occasionally delaminate from the printed circuit board or develop
cracks. This is due to stresses introduced into the chip by handling
of the PC board and stress due to thermal shock.
Vishay has introduced a chip in a molded package with flexible
terminations which does not change due to the above, i.e. no
cracks and no separation from the board.
The SMR3P is the industry’s lowest absolute TCR, thus reducing
a major source of uncertainty in precision circuits. The SMR3P
can withstand unconventional environmental conditions,
including the extremely high temperatures and radiation-rich
environments of down-hole oil exploration and well logging, or the
deep-sea underwater repeaters in cross-ocean communications.
The exceptionally-low TCR of the new Z-Foil Bulk Metal
®
Foil
resistor derives from an elegant balance of metallurgical resistivity
and temperature-induced compressive force.
The SMR3P comes with a Load Life Stability certificate:
The Bulk Metal Z-Foil resistor has documented the most precise
load-life stability of any resistor. That’s because the resistance
element is a Bulk Metal Z-alloy that has been applied to a
substrate with a unique formation of a resistive pattern that is
maintained stress-free through the balance of the process,
including termination welding, encapsulation, marking, curing,
etc. Coatings between the element and the external case isolate
the element from external stresses. The flat planar foil very
efficiently transmits heat to the substrate and dissipates it through
the leads and through the package body. The SMR series of
surface-mounts has the further advantage of flexible terminations
to isolate the element from repetitive expansions and contractions
of the board, thereby assuring even better long-term stability.
Moreover, all Vishay Bulk Metal Foil resistors are rated to
maintain rated stability at full rated power and temperature. So it
is not necessary to de-rate the foil resistors in application.
Application includes:
1. Secondary standards
2. Feedback devices for operational amplifiers
3. Precision voltage dividers
4. Precision bridge resistors
5. Decade voltage dividers

and make recommendations. For non-standard technical
