Notes
• Part marking: value; tolerance: due to resistor size limitations some resistors will be marked with only the resistance value
• Qualified to AEC-Q200 rev. D (1) For values above 0.1 Ω derate linearly to 80 % rated power at 0.5 Ω (2) WSL1206 0.0005 Ω to 0.00099 Ω is only available with 2 % tolerance (G tolerance code)

Notes
• Per PCN-DR-00009-2022-REV-0, WSL marking will be removed effective March 1st, 2023 (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 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 (3) Follow link for customization capabilities: www.vishay.com/doc?48163

Notes
(1) Consult factory for detailed TCR performance across temperature range associated with PCN-DR-00003-2020 for WSL0603. 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
