Power Metal Strip® Resistors, High Power,

Surface Mount, 4-Terminal

DESIGN SUPPORT TOOLS

FEATURES

•4-terminal design

• 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

• 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

(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.
