Notes

• “Temperature Coefficient of Resistance for Current Sensing” white paper: www.vishay.com/doc?30405

(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

(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

Notes

(1) PCN-DR-00003-2020 changed terminal height for WSLP0603 from 0.013" ± 0.005" for clad construction to 0.016" ± 0.005" for welded

construction

(2) PCN-DR-000023-2021-REV-1 changed terminal height for WSLP0805 from 0.013" ± 0.005" for clad construction to 0.016" ± 0.005" for

welded construction
