WSLS2512, Improved Stability
www.vishay.com
Vishay Dale
Power Metal Strip ? Resistors, Improved Stability
(0.25 % and 0.5 %), Low Value, 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 ? to 0.1 ? )
? All welded construction
? Solid metal nickel-chrome resistive element with low TCR
(< 20 ppm/°C)
? Very low inductance 0.5 neH to 2 nH
? Excellent frequency response to 50 MHz
? Low thermal EMF (< 3 μV/°C)
? AEC-Q200 qualified (1)
? Material categorization: For definitions of compliance
