INTRODUCTION
VSMP Series is the industry’s first device to provide high
rated power and excellent load life stability along with
extremely low TCR — all in one resistor.
One of the most important parameters influencing stability is
the Temperature Coefficient of Resistance (TCR). Although
the TCR of foil resistors is considered extremely low, this
characteristic has been further refined over the years. The
VSMP Series utilizes ultra high precision Bulk Metal® Z-Foil.
The Z-Foil technology provides a significant reduction of the
resistive element’s sensitivity to ambient temperature
variations (TCR) and to self heating when power is applied
(Power Coefficient of Resistance, or PCR). Along with the
inherently low PCR and TCR, Z-Foil technology also
provides remarkably improved load life stability, low noise
and tight tolerances.
The VSMP resistor has a full wraparound termination which
assures secure contact during the manufacturing process,
as well as providing stability during multiple thermal cyclings.

Notes
(1) IR and vapor phase reflow are recommended.
(2) Avoid the use of cleaning agents which could attack epoxy resins, which form part
of the resistor construction
(3) Vacuum pick up is recommended for handling
(4) If the use of a soldering iron becomes necessary, precautionary measures should
be taken to avoid any possible damage / overheating of the resistor
* Recommendation: The solder fillet profile should be such as to avoid running over
the top metallization

CRYOGENIC TEST
Different expansion/contraction rates of composite materials
in resistors may induce discontinuities during temperature
excursions that are not evident at temperature extremes,
making an unreliable resistor appear normal. A good resistor
must also return to its initial value with no resistance drift. In
this demo, a VFR VSMP0805 precision resistor is monitored
through the range of +25°C, down to -196°C and back up to
+25°C. Results confirm the VSMP0805 exhibits only 5
ppm/°C TCR, experiences no discontinuities, and returns to
its exact same starting value, showing absolutely no change
in resistance (< 1 ppm measurement accuracy).

PULSE TEST
TEST DESCRIPTION
All parts are baked at +125°C for 1 hour and allowed to cool
at room temperature for 1 hour, prior to testing. By using an
electrolytic 0.01µF capacitor charged to 1200 VDC, a single
pulse was performed on 30 units of 1206, 10 k of Surface
Mount Vishay Foil resistor and Thin Film resistor. The units
were allowed time to cool down, after which the resistance
measurements were taken and displayed in ppm deviation
from the initial reading.
TEST RESULTS
FIGURE 8 - PULSE TEST DESCRIPTION
Catastrophic Damage - occurs when the ESD event causes
the device to immediately stop functioning. This may occur
after one or a number of ESD events with diverse causes,
such as human body discharge or the mere presence of an
electrostatic field.
Latent Damage - occurs when the ESD event causes
moderate damage to the device, which is not noticeable, as
the device appears to be functioning correctly. However, the
load life of the device has been dramatically reduced, and
further degradation caused by operating stresses may cause
the device to fail during service. Latent damage is the source
for greatest concern, since it is very difficult to detect by
re-measurement or by visual inspection, because damage
may have occurred under the external coating.

By using an electrolytic 500 pF capacitor charged up to 4500

different Surface Mount Chip Resistors technologies, with an
initial voltage spike of 2500 V (Figure 10). The units were
allowed time to cool down, after which the resistance
measurements were taken and displayed in ppm deviation
from the initial readings. Readings were then taken in 500 V

ELECTROSTATIC DISCHARGE (ESD)
ESD can be categorized into three types of damages:
Parametric Failure - occurs when the ESD event alters one
or more device parameters (resistance in the case of
resistors), causing it to shift from its required tolerance. This
failure does not directly pertain to functionality; thus a
parametric failure may be present while the device is still
functional.

PRECISION CENTER
Precision centers are located around the world to provide local, short run, quick delivery of Vishay Bulk Metal® Foil resistors.
Unique to Vishay Foil Resistors (VFR) is the ability to provide any value to any tolerance. The precision centers can ship small
quantities in five days or less.
Why do we have authorized local manufacturing or precision centers?
Because we have no standard values and each resistor is trimmed to the precise value ordered. The unique chain of Precision
Centers brings these precise values as close as possible to the circuit designers in the shortest time possible.
