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
• All welded construction of the Power Metal
Strip® resistors are ideal for all types of current
sensing, voltage division, and pulse applications
Available
• Proprietary processing technique produces
extremely low resistance values (0.01 Ω to 0.1 Ω)
• Solid metal nickel-chrome resistive element with
low TCR (< 20 ppm/°C)
