Power Metal Strip® Resistors, High Power (10 W),
Low Value (Down to 0.001 Ω), Surface-Mount
FEATURES
• Improved thermal management incorporated
into design
• All welded construction of the Power Metal Strip
resistors are ideal for all types of current
sensing, voltage division, and pulse applications
• Proprietary processing technique produces
extremely low resistance values
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• Very low inductance (< 5 nH)
• Low thermal EMF (< 3 μV/°C)
• Solid metal nickel-chrome or manganese-copper alloy
resistive element with low TCR
(< 20 ppm/°C)
• AEC-Q200 qualified (1)

Component TCR - total TCR that includes the TCR effects of the resistor element and the copper terminal
Element TCR - only applies to the alloy used for the resistor element; refer to item 1 in the construction illustration on the following page
Maximum working voltage - the WSHP is not voltage sensitive, but is limited by power / energy dissipation and is also not ESD sensitive
Typical TCR is positive, for more details contact factory

Note
•
Sensing locations are based on the construction of the part; terminals are wrapped from the outside to underneath. These options place the
sensing location nearest the temperature stable resistance element, which minimizes contact resistance and optimizes TCR
