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)
