Power Metal Strip® Resistors, High Power (2 x Standard WSL),
Low Value (Down to 0.0005 Ω), Surface-Mount
LINKS TO ADDITIONAL RESOURCES
FEATURES
• 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
0.0005 Ω)
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• 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
Notes
• This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details
• Follow link to Overview of Automotive Grade Products for more details: www.vishay.com/doc?49924
(1) Flame retardance test may not be applicable to some resistor technologies
Notes
• Part marking: value; tolerance: due to resistor size limitations some resistors will be marked with only the resistance value
(1) WSL1206...18 0.0005 Ω to 0.00099 Ω is only available with 2 % tolerance (G tolerance code)
Notes
(1) WSL marking (www.vishay.com/doc?30327); WSL decade values (www.vishay.com/doc?30117)
(2) Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes that designate 1000 piece reel quantities. These
non-standard packaging codes are identical to our standard EA (lead (Pb)-free) and TA (tin / lead), except that they have a package quantity
of 1000 pieces

Notes
(1) Consult factory for detailed TCR performance across temperature range associated with PCN-DR-00003-2020 for WSL0603...18. TCR
performance is improved for +25 °C to +155 °C
(2) Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
(3) Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page
(4) Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
DIMENSIONS in inches (millimeters)
