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 0.0001 Ω
Sulfur resistance by construction that is unaffected by high sulfur environments
Solid metal iron-chrome 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)
Flame retardance test may not be applicable to some resistor technologies
Qualified to AEC-Q200 rev. D
Other values may be available, contact factory
WSL marking (www.vishay.com/doc?30327)
Packaging code: EB (lead (Pb)-free) is a non-standard packaging code that designates a 1000 piece reel size. The non-standard packaging code is identical to our standard EA (lead (Pb)-free) packaged code, except that it has a package quantity of 1000 pieces

Consult factory for detailed TCR performance across full temperature range as performance is resistance value specific
Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page
Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
