Notes

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

(1) Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal

(2) Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page

(3) Maximum working voltage - the WSL is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive

(4) Typical TCR is positive, for more details contact factory
