WSLS2512, Improved Stability  
Vishay Dale  
Improved Stability (0.25 % and 0.5 %), Power Metal Strip® Resistors  
Low Value (0.01 Ω to 0.1 Ω), Surface Mount  
FEATURES  
• Current sensing in high-temperature (+ 125 °C)  
applications  
• Greater stability with maximum resistance  
change of 0.25 % or 0.5 % through 2000 h  
workload  
• Ideal for all types of current sensing, voltage  
division and pulse applications including  
switching  
and  
linear  
power  
supplies,  
instruments, power amplifiers and shunts  
• Proprietary processing technique produces extremely low  
resistance values (0.01 Ω to 0.1 Ω)  
• All welded construction  
• Solid metal Nickel-Chrome resistive element with low TCR  
(< 20 ppm/°C)  
• Lead (Pb)-free construction is RoHS compliant  
• Very low inductance 0.5 nH to 2 nH  
• Excellent frequency response to 50 MHz  
• Low thermal EMF (< 3 µV/°C)
