Power Metal Strip® Resistors,
Low Value (Down to 0.0003 Ω), Surface-Mount
FEATURES
• Power Metal Strip® all-welded construction is
ideal for all types of current sensing, voltage
division, and pulse applications
• Solid metal nickel-chrome, manganese-copper,
or manganese-copper-tin alloy resistive
element with low TCR (< 20 ppm/°C)
• Proprietary processing technique produces
extremely low resistance values, down to
0.0003 Ω
LINKS TO ADDITIONAL RESOURCES
• Sulfur resistance by construction that is unaffected by
high sulfur environments
3
D
• Very low inductance (< 2 nH)
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified (1)
