Power Metal Strip® Resistors, High Power (2 x Standard WSL),
Low Value (Down to 0.0005 ), 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
0.0005 )
• 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
• Excellent frequency response to 50 MHz
• Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified available
• Compliant to RoHS Directive 2002/95/EC
Notes
*Pb containing terminations are not RoHS compliant, exemptions
may apply
** Please see document “Vishay Material Category Policy”:
