Power Metal Strip® Resistors, High Power (2 x Standard WSL),
Low Value (down to 0.0005 ), Surface Mount
DESIGN SUPPORT TOOLS
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 )
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.
Note
Part marking: Value; tolerance: Due to resistor size limitations some resistors will be marked with only the resistance value.
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) 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; refer to item 1 in the construction illustration on the following page#
(3) Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
