FEATURES
• Temperature coefficient of resistance (TCR)(see table 1
and fig. 3):
±0.05 ppm/°C nominal (0°C to +60°C, +25°C ref)
±0.2 ppm/°C nominal (–55°C to +125°C, +25°C ref.)
• Resistance tolerance: to ±0.02%
• Power coefficient “∆R due to self heating”: 5 ppm at
rated power
• Power rating: to 400 mW at +70°C (see table 2)
Load life stability: ±0.02% after 2,000 hrs at 70°C at
rated power.
• Resistance range: 10 Ω to 75 kΩ (for higher and lower
values, please contact us)
• Vishay Foil resistors are not restricted to standard
values; specific “as required” values can be supplied at
no extra cost or delivery (e.g., 1K2345 vs. 1K)
• Thermal stabilization time: <1 s (within 10 ppm of steady
state value)
• Electrostatic discharge (ESD): at least to 25 kV
• Short time overload: ≤0.005%
• Rise time: 1 ns, effectively no ringing
• Current noise: <0.010 μV
RMS
/V of applied voltage
(<–40 dB)
• Voltage coefficient: <0.1 ppm/V
• Non-inductive: <0.08 μH
• Non-hot spot design
• Terminal finishes available: tin/lead alloy
• Matched sets are available on request
• Prototype quantities available in just 5 working days or
sooner. For more information, please contact us.
• For higher temperature application up to +240°C and for
better performances, please contact us.
• Adding “U” to the model number (example: 303261U).
These units have all of the Table 2A (page 5) 100% tests
performed, with no destructive qualification testing
required (Table 3A, page 6). For more information,

INTRODUCTION
The 303261 through 303266 series, tested per
EEE-INST-002 and MIL-PRF-55342, is based on the new
generation Z-1 technology of the Bulk Metal
®
precision foil
resistor elements by Vishay Precision Group (VPG), which
makes these resistors virtually insensitive to destabilizing
factors. Their element, based on the new Z-1 Foil, is a
solid alloy that displays the desirable bulk properties of
its parent material; thus, it is inherently stable (remarkably
improved load life stability of 25 ppm), noise-free and
withstands ESD to 25 kV or more. The alloy is matched
to the substrate and forms a single entity with balanced
temperature characteristics for an unusually low and
predictable TCR over a wide range from –55°C to +150°C.
Resistance patterns are photo-etched to permit trimming
of resistance values to very tight tolerances.
The 303261 through 303266 series has a full wraparound
termination which ensures reliable handling during the
manufacturing process, as well as providing stability
during multiple thermal cycles.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
