Power Metal Strip
®
Resistors, High Power,
Surface Mount, 4-Terminal
FEATURES
•4-terminal design
• Ideal for all types of current sensing, voltage
division and pulse applications
• Proprietary processing technique produces
extremely low resistance values
• Durable with all-welded construction
• All welded construction
• Solid metal nickel-chrome or manganese-
copper resistive element with low TCR
(< 20 ppm/°C)
• Low thermal EMF (< 3 μV/°C)
• Material categorization: for definitions of compliance
please see
www.vishay.com/doc?99912
Notes
• Part marking: due to resistor size limitation, parts will be marked with only the resistance value.
• Resistance values are available per WSL decade table (www.vishay.com/doc?30117).
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.

Note
(1)
Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes designating 1000 piece reels. These non-standard
packaging codes are identical to our standard EA (lead (Pb)-free) and TA (tin / lead), except that they have a package quantity of 1000 pieces.
