Vishay Foil Resistors  
Models 303134 through to 303138 (Ultra High Precision Surface Mount Chip  
Resistors, VSMP Z-Foil Technology Configuration), Screen/TestFlowinCompliance

power  
INTRODUCTION  
Resistance range: 10 to 75 k  
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@vishaypg.com  
Our application engineering department is available to  
advise and make recommendations.
