SMR1D/SMR3D  
Vishay Foil Resistors  
High Precision Bulk Metal® Foil Molded Surface Mount Resistor  
with TCR down to ꢀ ꢁꢁp/ꢂC, Flexible Terpinations,  
and Load Life Stability of ꢃ0ꢃꢃꢄ ꢅ (ꢄꢃ ꢁꢁp)  
FEATURES  
• Temperature coefficient of resistance (TCR):  
2 ppm°C typical (- 55 °C to + 125 °C,  
Pb-free  
+ 25 °C ref.)  
Available  
• Tolerance: to 0.01 %  
RoHS*  
• Flexible terminations ensure minimal stress  
transference from the PCB due to a difference  
in thermal coefficient of expansions (TCE)  
COMPLIANT  
Any value at any tolerance available within resistance range  
• Electrostatic discharge (ESD) above 25 000 V  
• Load life stability: 0.005 % (70 °C, 2000 h at rated power)  
INTRODUCTION  
The SMRxD is a precision molded surface mountable  
resistor offering all the elements of precision; including low  
TCR, tight tolerance, long term stability, low noise, low  
thermal EMF, and non-measurable voltage coefficient. It  
utilizes the Bulk Metal® Foil technology for the resistive  
element with its inherent low and predictable TCR and long  
term stability. This surface mountable product affords similar  
performance to the time tested S series molded through-hole  
product.  
• Resistance range: 5 Ω to 80 kΩ (for higher and lower  
values, please contact us)  
• Power rating: to 600 mW at 70 °C  
• Non inductive, non capacitive design  
• Current noise: - 40 dB  
• Voltage coefficient: < 0.1 ppm/V  
• Non inductive: < 0.08 µH  
• Non hot spot design  
• Terminal finishes available: lead (Pb)-free  
tin/lead alloy  
The flexible terpinations of this ꢁroduct also reduce  
stress transference frop the PCB to the resistor0  
• Matched sets with TCR tracking are available upon request  
• Any value available within resistance range (e.g. 1K234)  
• Prototype samples available from 48 h. For more  
information, please contact foil@vishay.com  
Voltage division with tight tracking < 3 ppm/°C can be  
achieved with 2 randoply selected units even with a large  
ratio between the two values.

For better performances please review SMRxDZ datasheet  
Our Application Engineering Department is available to  
advise and make recommendations. For non-standard  
technical requirements and special applications, please
