Power Metal Strip® Resistors, Very High Power (1 W),
Low Value (Down to 0.005 Ω), Surface-Mount
FEATURES
• Very high power to foot print size ratio (1 W in
0805 / 2 W in 1206 package)
• All welded construction of the Power Metal
Strip® resistors is ideal for all types of current
sensing, voltage division and pulse applications
• Proprietary processing technique produces
extremely low resistance values (down to
0.005 Ω)
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• 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
LINKS TO ADDITIONAL RESOURCES
• Excellent frequency response to 50 MHz
• Low thermal EMF (< 3 μV/°C)
