Sulfur resistance by construction that is unaffected by high sulfur environments
Solid metal nickel-chrome or manganese- copper resistive element with low TCR (< 20 ppm/°C)
All welded construction
Low thermal EMF (< 3 µV/°C)
Part marking: due to resistor size limitation, parts will be marked with only the resistance value
Resistance values are available per WSL decade table (www.vishay.com/doc?30117)
Per PCN-DR-00009-2022-REV-0, WSL marking will be removed effective March 1st, 2023
Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes designating 1000 piece reels. 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
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
