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
