FEATURES
• Temperature coefficient of resistance (TCR):
0.0ꢀ ppmꢁ/C nominal (0/C to ꢂ 60/C)
0.2 ppmꢁ/C nominal (ꢃꢀꢀ/C to ꢂ12ꢀ/Cꢄ ꢂ2ꢀ/C ref.)
(see Table 1 and Figure 2)
• Tolerance: to 0.01ꢅ (100 ppm)
• Power coefficient “∆R due to self heating” ꢀ ppm at
rated power
• Load-life stability (70/C for 2000 h): 0.00ꢀꢅ (ꢀ0 ppm)
• Power rating to: 600 mW at ꢂ70/C
in the most critical applications by eliminating the need for
corrective circuitry and reducing the large land patterns
needed for a wrap-around configuration. The device’s flip-
chip configuration saves up to 3ꢀꢅ PCB space compared
with a surface-mount chip with wraparound terminations
while also providing better strain relief to eliminate
cracked substrates and board delamination.
• Electrostatic discharge (ESD): at least to 2ꢀ kV
• Resistance range: ꢀ Ω to 12ꢀ kΩ (for lower and higher
valuesꢄ please contact us)
• Foil resistors are not restricted to standard values;
specific “as required” values can be supplied at no
extra cost or delivery (e.g.ꢄ 1K234ꢀ vs. 1K)
In addition to its remarkably improved load-life stabilityꢄ
the VFCP Series is noise-free and provides ESD
• Non-inductiveꢄ non-capacitive design
protection of 2ꢀ kV or more for increased reliability. The
device’s solid element alloy is matched to the substrateꢄ
forming a single entity with balanced resistance versus
temperature characteristics for an unusually low and
predictable TCR over a wide temperature range from
ꢃꢀꢀ/C to more than ꢂ12ꢀ/C. The adhesive that holds the
foil to the flat substrate withstands high temperaturesꢄ
pulsing powerꢄ moisture incursionsꢄ shock and vibrationꢄ
and low-temperature exposure while still holding securely
to the foil element. Resistance patterns are photo-etched
into the element to permit the trimming of resistance
values to very tight tolerances as low as 0.01ꢅ.
• Thermal stabilization time: <1 s (within 10 ppm of
steady state value)
• Short time overload: ≤0.00ꢀꢅ (ꢀ0 ppm)
• Non hot spot design
• Rise time: 1 ns effectively no ringing
• Current noise: <0.010 μVrms ꢁ V of applied voltage
(<ꢃ40 dB)
• Voltage coefficient: <0.1 ppmꢁV
• Non-inductive: <0.08 μH
The Flip Chips devices are qualified as anti-sulfurated
resistors for use in environments with high levels of
contamination. Such environments include alternative
energy applicationsꢄ industrial control systemsꢄ
sensorsꢄ RTDsꢄ electric instrumentationꢄ weather and
communication base stationsꢄ and any electronic
appliance used in high concentrations of sulfur. The
combination of flip-chip terminations and Z-Foil
construction and materials results in the most stable
resistors availableꢄ requiring the lowest error allowance.
This means that more error allowance can be transferred
to active devices—resulting in lower costs—or applied
to the foil resistors themselvesꢄ allowing for looser initial
tolerances than would be required for other resistor
technologies.
• Terminal finishes available: lead (Pb)-freeꢄ tinꢁlead alloy
• Compliant to RoHS directive 2002ꢁ9ꢀꢁEC*
• Matched sets are available per request
• Prototype quantities available in just ꢀ working days or
sooner. For more informationꢄ please contact us.
INTRODUCTION
Based on VFR’s next-generation Bulk Metal® Z-Foil
technologyꢄ the VFCP Series (foil resistor flip-chip)
excels over all previous stability standards for precision
resistors with an order of magnitude improvement in
high-temperature stabilityꢄ load-life stabilityꢄ and moisture
resistance. These new benchmark levels of performance
provide design engineers with the tools to build circuits
not previously achievable while reducing costs and space
