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
