FEATURES
•Power Metal Strip
®
all-welded construction is
ideal for all types of current sensing, voltage
division, and pulse applications
• Proprietary processing technique produces
extremely low resistance values, down to
0.0003
• Solid metal nickel-chrome, manganese-copper,
or manganese-copper-tin alloy resistive
element with low TCR (< 20 ppm/°C)
• Construction is unaffected by high sulfur
environments
• Very low inductance (< 2 nH)
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified
(1)
• Material categorization: for definitions of compliance

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
