Design Tools
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) • AEC-Q200 qualified (1)
• Material categorization: for definitions of compliance please see www.vishay.com/doc?99912

RESISTOR CHARACTERISTICS ± 75 for 0.5 mΩ to 5 mΩ ± 110 for 0.3 mΩ ± 75 for 0.2 mΩ < 20 -65 to +170 (P x R)1/2
Notes
(1) Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal (2) Element TCR - only applies to the alloy used for the resistor element (3) Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
