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 Bulk Metal® Foil is considered
extremely low, this characteristic has been further
refined over the years. The VSMP Series utilizes ultra
high precision 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.
Vishay Foil Resistors’ (VFR) application engineering
department is available to advise and make
recommendations. For non-standard technical
requirements and special applications, please contact

* This datasheet provides information about parts that are RoHS-compliant and/or parts that are non-RoHS-compliant.
For example, parts with lead (Pb) terminations are not RoHS compliant. Please see the information/tables in this datasheet for details.

Note
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 reduces the effect of “hot spots” and
improves the long-term stability of Bulk Metal Foil resistors.

Figure 4—Recommended Mounting
*
1. IR and vapor phase reflow are recommended.
2. Avoid the use of cleaning agents that 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.

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 0.01 μF capacitor charged to
1200VDC, a single pulse was performed on 30 units of
1206, 10 kΩ of Surface Mount Bulk Metal® 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.

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.
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.
Test Description
By using an electrolytic 500 pF capacitor charged up to
4500 V, pulses were performed on 10 units of 1206,
10 kΩ of three 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 increments up to 4500 V.
