WSL...18 High Power

Vishay Dale

Power Metal Strip^®Resistors, High Power (2 x Standard WSL),

Low Value (Down to 0.001 ), Surface Mount

FEATURES

• Ideal for all types of current sensing, voltage

division and pulse applications including

switching and linear power supplies,

instruments, power amplifiers

• Proprietary processing technique produces

extremely low resistance values (down to

0.001 )

• Specially selected and stabilized materials

allow for high power ratings (2 x standard WSL

rating)

• All welded construction

• Solderable terminations

• Very low inductance 0.5 nH to 5 nH

• Solid metal nickel-chrome or manganese-copper alloy

resistive element with low TCR (< 20 ppm/°C)

• Excellent frequency response to 50 MHz

• Low thermal EMF (< 3 μV/°C)

• AEC-Q200 qualified available

• Compliant to RoHS Directive 2002/95/EC
