The Future COTS Bulk Metal
®
Foil Resistors are Already Here
The Future COTS Bulk Metal® Foil Resistors are Already Here
with Flexible Terminations System and
Load-Life Stability of 0.005% (50 ppm)
FEATURES AND BENEFITS
• Temperature coefficient of resistance (TCR):
±0.2 ppm/°C typical (–55°C to +125°C, +25°C ref.)
• Tolerance: to ±0.01%
• Power coefficient of resistance “∆R due to self heating:”
5 ppm at rated power
• Electrostatic discharge (ESD) at least to 25 kV
• Load-life stability: ±0.005% (70°C, 2000 h)
• Resistance range: 5
Ω
to 80 kΩ (for higher and lower
values, please contact us)
• Bulk Metal Foil resistors are not restricted to standard
values; we can supply specific “as required” values at
no extra cost or delivery (e.g., 1K01234 vs. 1 k)
• Power rating: to 600 mW at +70°C
• Thermal stabilization time: <1 s (within 10 ppm of
steady state value)
• Non inductive, non capacitive design
• Current noise: 0.010 μV
RMS
/V of applied voltage
(<–40 dB)
• Voltage coefficient: <0.1 ppm/V
• Low harmonic distortion, linear behavior
• Non hot spot design
• Inductive: <0.08 μH
• Terminal finishes available: lead (Pb)-free, tin/lead alloy,
or silver
Flexible terminations assure minimal stress
transference from the PCB due to a difference
in thermal coefficient of expansions (TCE).
generation of Bulk Metal
®
Foil technology, Z Foil, the
Flex Series' flexible terminations system is designed to
establish pliability while maintaining terminal strength,
solderability, stability, and electrical specifications.
The flexible terminations absorb board stresses, thereby
prevening external stresses from reaching the resistance
element.
Why choose the Flex Series
• Provides superior flex performance compared to
standard terminations systems
• Flexible terminations isolate resistor body from PCB
stresses
• Superior flex performance up to several mm
Stress checklist:
1. Where is the resistor going to be placed? Around big or
heavy components? Solution: Flex Series.
2. Are you intending to place the resistor close to the PCB
edges or corners? (Stress can occur due to bending or
CTE difference.) Solution: Flex Series.
3. Will the PCB be exposed to high levels of boards
flexure during assembly or mounting? Solution: Flex
Series.
INTRODUCTION
When mounted on a board that is bent or flexed either
during the manufacturing process or in the field,
resistors can develop cracks that affect their electrical
performances. The Flex Series is a surface-mount, multi-
featured precision resistor that incorporates a unique
flexible terminations system. Integrated with the latest

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.
