Vishay Dale
Power Metal Strip® Resistors, High Power (10 W),
Low Value (Down to 0.001 Ω), Surface-Mount
FEATURES
• Improved thermal management incorporated
into design
• All welded construction of the Power Metal
Strip resistors are ideal for all types of current
sensing, voltage division, and pulse
applications
• Proprietary processing technique produces
extremely low resistance values
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• Very low inductance (< 5 nH)
• Low thermal EMF (< 3 μV/°C)
• Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• AEC-Q200 qualified (1)
• PATENT(S): www.vishay.com/patents
• Material categorization: for definitions of compliance
