PARAMETER UNIT RESISTOR CHARACTERISTICS
-300 / +50 for 0.5 m to 0.99 m
Component temperature coefficient
(1)
(including terminal) ppm/C 150 for 1 m and 2 m
TCR measured from -55 C to 150 C
75 for 3 m to 5 m
(2)
Element TCR ppm/C < 20
Operating temperature range C -65 to +170

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