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)
Consult factory for detailed TCR performance across temperature range associated with PCN-DR-00003-2020 for WSLP0603. TCR
performance is improved for +25 C to +155 C

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
