High Power - Excellent Long Term Stability
FEATURES
• Excellent Load Life Stability: (+70°C for 2000 hours)
± 0.005% at 100mW
± 0.01% at 200mW
• High Rated Power at +70°C: 200mW
• Low TCR to ± 2ppm/°C (see table 1)
• Tight Tolerance to ± 0.01% (see table 1)
INTRODUCTION
• Resistance Range: 10Ω to 12KΩ (for lower and
higher values please contact us)
VSMP0805 is the industry’s first device to provide higher
power rating with excellent long term stability along with
low nominal TCR of ± 0.5ppm/°C (-55°C to +125°C) all in
one.
• Shelf Life Stability: 50ppm/year (0.005%) maximum ∆R
• Voltage Coefficient: < 0.00001%/volt (< 0.1ppm/V)
• Current Noise: - 40DB: < 0.01µV(RMS)/volt of applied
The VSMP0805 Precision Surface Mount Chip Resistor
utilizes Ultra Precision Bulk Metal® Z Foil (BMZF) Vishay’s
revolutionary for the resistive element. This technology
provides a significant reduction of the resistive components’
sensitivity to ambient temperature variations and applied
power changes. Designers now can guarantee a high degree
of stability an accuracy in fixed - resistor applications using
solutions based on BZMF technology.
voltage
• Non Inductive: < 0.08µH
• Low Thermal EMF: < 0.1µV/°C maximum
• Maximum Weight: 6 (mg)
• Terminal Finishes Available:
Lead (Pb)-free (Sn 99.3% Cu 0.7%)
Tin/Lead Alloy (Sn 62% Pb 36% Ag 2%)
The new technology provides inherently an extremely low
and predictable Temperature Coefficient of Resistance
(TCR), a remarkably improved load life stability, low noise
and availability of tight tolerance.

RESISTANCE VALUE (MIL Range)
The TCR is a process capability not a selection process and
for most of the range is independent of ohmic value and lot
related variations.

A voltage divider can be fashioned by using two arbitrarily
selected VSMP0805s with a resultant tracking specification
of < 3ppm/°C. Extremely low tracking of < 1ppm/°C can be
supplied upon request.

The VSMP0805 has a conventional full wrap around robust
termination which insures safe handling during manufacturing
process, as well as providing stability during the multiple
thermal cyclings it will see over its service life.

The availability of tight absolute tolerance provides a good
cost solution for the variability of other components when
compiling the total error budget. BMZF offers the best
stability available; and is more than an order of magnitude
better than thin film technology. The noise generated by
the resistor is non measurable and its design and
construction make it well suited for high frequency
applications. The BMZF is the ultimate resistor component
for analog applications.
APPLICATIONS
• Automatic Test Equipment (ATE)
• High Precision Instrumentation
• Laboratory, Industrial and Medical
• Audio (High End Stereo Equipment))
Most effective in applications where high stability is
required under load and extreme enviromental conditions.
• EB Applications (electron beam scanning and recording
equipment, electron microscopes)
