FEATURES  
Ω,  
Temperature coefficient of resistance:  
± 15 ppm/°C max. (- 55 °C to + 125 °C, + 25 °C  
ref.); ± 10 ppm/°C max. (- 55 °C to + 125 °C,  
+ 25 °C ref.) is available on request (see table 1)  
Power rating: 1 W to 3 W  
Resistance tolerance: ± 0.1 %  
Resistance range: 1 mΩ to 200 mΩ (1)  
No minimum order quantity and any value at any  
tolerance available within resistance range.  
Vishay Foil resistors are not restricted to standard values,  
specific “as required” values can be supplied at no extra  
cost or delivery (e.g. 2.3456 mΩ vs. 2 mΩ)  
Load life stability to ± 0.2 % (70 °C, 2000 h at rated power)  
Short time overload: ± 0.1 % typical  
Vishay Foil Resistors’ application engineering department is  
available to advise and make recommendations.
