Power Metal Strip® Resistors, Low Value,
High Power, Surface Mount, 4-Terminal
FEATURES
• 4-terminal design allows for 1 % tolerance
down to 0.0002 Ω
• High power to foot print size ratio
• 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, down to
0.0002 Ω
• Sulfur resistance by construction that is unaffected by
high sulfur environments
• Solid metal nickel-chrome, manganese-copper-tin, or
manganese-copper alloy resistive element with low TCR
(< 20 ppm/°C)
• Very low inductance 0.5 nH to 5 nH
• Low thermal EMF (< 3 μV/°C)

Notes
(1)
Packaging code: EB (lead (Pb)-free) is non-standard packaging code designating 1000 piece reels. These non-standard packaging code is
identical to our standard EA (lead (Pb)-free), except that they have a package quantity of 1000 pieces
