Power Metal Strip^® Resistors, Low Value,
High Power, Surface Mount, 4-Terminal
WSL2726
Vishay Dale
FEATURES
• 4-Terminal design allows for 1 % tolerance
down to 0.0003 
• High power to foot print size ratio
• 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, down to 0.0005 
• All welded construction
• Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• Very low inductance 0.5 nH to 5 nH
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified available ⁽¹⁾
• Compliant to RoHS Directive 2002/95/EC
