303139, 303140  
Vishay Foil Resistors  
Models # 303139 and 303140 - Molded Surface Mount Space and Military  
Grade Resistors SMRxDZ with Screen/Test Flow in Compliance with  
EEE-INST-002, (Tables 2A and 3A, Film/Foil, Level 1) and MIL-PRF-55182  
FEATURES  
• Temperature coefficient of resistance (TCR):  
± 0.2 ppm°C typical (- 55 °C to + 125 °C, + 25 °C ref.)  
• Tolerance: to ± 0.02 %  
• Power coefficient of resistance (PCR)  
“ΔR due to self heating”: 5 ppm at rated power  
• Flexible terminations ensure minimal stress transference  
from the PCB due to a difference in thermal coefficient of  
expansions (TCE)  
• Electrostatic discharge (ESD) up to 25 000 V  
• Load life stability: ± 0.005 % (70 °C, 2000 h at rated power)  
INTRODUCTION  
• Resistance range: 5 Ω to 40 kΩ  
The 303139, 303140 are ultra high precision molded surface  
• Vishay Foil resistors are not restricted to standard values;  
mountable resistors offering all the elements of precision;  
specific “as requested” values can be supplied at no extra  
including low TCR, tight tolerance, long term stability, low  
cost or delivery (e.g. 1K2345 vs. 1K)  
noise, low thermal EMF, and non-measurable voltage  
• Maximum power: to 600 mW at 70 °C  
coefficient. One of the 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. These resistors utilize ultra high precision Bulk Metal®  
Z-Foil.  
• Non-inductive, non-capacitive design  
• Current noise: - 40 dB  
• Voltage coefficient: < 0.1 ppm/V  
• Non-inductive: < 0.08 µH typical  
• Non hot spot design  
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).  
• Terminal finish: tin/lead alloy  
• Matched sets with TCR tracking are available upon  
request  
Voltage division with tight tracking < 2 ppm/°C can be  
achieved with 2 randomly selected units even with a large  
ratio between the two values.  
• For oriented performances please contact us  
•
For prototype units, append a “U” to the model number  
(example: 303139U). These units pass all tests per table 3  
(page 4) with no destructive qualification testing required  
(table 4, page 4). For more information, please contact  
foil@vishaypg.com
