Notes
(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
