Ultra High-Precision Z-Foil Flip Chip Resistor
Ultra High-Precision Z-Foil Flip Chip Resistor
with TCR of 0ꢀ2 ppꢁm/C, ꢂ5ꢃ Space Saꢄing ꢄsꢀ ꢅraparound Design
and PCR of 5 ppꢁ at Rated Power
FEATURES
• Temperature coefficient of resistance (TCR):
0.2 ppmꢀ/C typical (ꢁ55/C to ꢂ125/Cꢃ ꢂ25/C ref.)
• Tolerance: to 0.01ꢄ (100 ppm)
• Power coefficient “∆R due to self heating” 5 ppm at
rated power
• Load-life stability (70/C for 2000 h): 0.005ꢄ (50 ppm)
• Power rating to: 600 mW at ꢂ70/C
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 35ꢄ 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 25 kV
• Resistance range: 5 Ω to 125 kΩ (for lower and higher
valuesꢃ please contact us)
• Bulk Metal® Foil resistors are not restricted to standard
values; specific “as required” values can be supplied at
no extra cost or delivery (e.g.ꢃ 1K2345 vs. 1K)
In addition to its remarkably improved load-life stabilityꢃ
the VFCP Series is noise-free and provides ESD
• Non-inductiveꢃ non-capacitive design
• Thermal stabilization time: <1 s (within 10 ppm of
steady state value)
protection of 25 kV or more for increased reliability. The
device’s solid element alloy is matched to the substrateꢃ
forming a single entity with balanced resistance versus
temperature characteristics for an unusually low and
predictable TCR over a wide temperature range from
ꢁ55/C to more than ꢂ125/C. The adhesive that holds the
foil to the flat substrate withstands high temperaturesꢃ
pulsing powerꢃ moisture incursionsꢃ shock and vibrationꢃ
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 0.01ꢄ.
• Short time overload: ≤0.005ꢄ (50 ppm)
• Non hot spot design
• Rise time: 1 ns effectively no ringing
• Current noise: <0.010 μVrms ꢀ V of applied voltage
(<ꢁ40 dB)
• Voltage coefficient: <0.1 ppmꢀV
• 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 applicationsꢃ industrial control systemsꢃ
sensorsꢃ RTDsꢃ electric instrumentationꢃ weather and
communication base stationsꢃ 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 availableꢃ 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 themselvesꢃ allowing for looser initial
tolerances than would be required for other resistor
technologies.
• Terminal finishes available: lead (Pb)-freeꢃ tinꢀlead alloy
• Compliant to RoHS directive 2002ꢀ95ꢀEC*
• Matched sets are available per request
• Rapid prototype sample quantities are available.

INTRODUCTION
Based on VFR’s Bulk Metal Z-Foil technologyꢃ 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 stabilityꢃ
load-life stabilityꢃ 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 in the most
