Vishay Foil Resistors
Models 303134 through to 303138 (Ultra High Precision Surface Mount Chip
Resistors, VSMP Z-Foil Technology Configuration), Screen/TestFlowinCompliance
with EEE-INST-002, (Tables 2A and 3A, Film/Foil, Level 1) and MIL-PRF-55342
FEATURES
• Temperature coefficient of resistance (TCR):
0.05 ppm/°C typical (0 °C to + 60 °C)
0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)
• Tolerance: to 0.02 %
• Power coefficient “ΔR due to self heating”:
5 ppm at rated power
• Power rating: to 400 mW at + 70 °C
Top View
• Load life stability: to 0.03 % at 70 °C, 2000 h at rated
power
INTRODUCTION
• Resistance range: 10 Ω to 75 kΩ
The 303134 through to 303138 series is the first surface
mount device to provide high rated power, excellent load life
stability along with extremely low TCR all in one resistor.
• Vishay Foil resistors are not restricted to standard values,
we can supply specific “as required” values at no extra cost
or delivery (e.g. 1K2345 vs. 1K)
• Fast thermal stabilization < 1 s
• Electrostatic discharge (ESD) up to 25 000 V
• Short time overload: ≤ 0.02 %
• Non-inductive, non-capacitive design
• Rise time: 1 ns effectively no ringing
• Current noise: - 42 dB
One of the most important parameters influencing stability is
the temperature coefficient of resistance (TCR). Although the
TCR of foil resistors is considered extremely low, this
characteristic has been further refined over the years. The
303134 through to 303138 Series utilizes ultra high precision
Bulk Metal® Z-Foil. The Z-Foil technology provides a
significant reduction of the resistive element’s sensitivity to
ambient temperature variations (TCR) and to self heating
when power is applied (power coefficient). Along with the
inherently low PCR and TCR, Z-Foil technology also
provides remarkably improved load life stability, low noise
and availability of tight tolerance.
• Voltage coefficient < 0.1 ppm/V
• Non-inductive: < 0.08 µH
• Non hot spot design
• Terminal finish: tin/lead alloy
• Matched sets are available on request
The 303134 through to 303138 series has a full wraparound
termination which ensures safe handling during the
manufacturing process, as well as providing stability during
multiple thermal cyclings.
• For prototype units, append a “U” to the model number
(example: 303134U). These units have all of the table 2A
(page 3) 100 % tests performed, with no destructive
qualification testing required (table 3A, page 4). For more
information, please contact foil@vishay.com
Our application engineering department is available to
advise and make recommendations.
