Power Metal Strip® Resistors, Very High Power (to 15 W),

Low Value (Down to 0.0001

), Surface-Mount

LINKS TO ADDITIONAL RESOURCES

FEATURES

• 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, down to

0.0001



• Sulfur resistance by construction that is

unaffected by high sulfur environments

• Specially selected and stabilized materials allow for high

power rating (to 15 W)

• Very low inductance 0.5 nH to 5 nH

• Low thermal EMF (< 3 μV/°C)

• AEC-Q200 qualified (1)

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

Notes

• Follow link to Overview of Automotive Grade Products for more details: www.vishay.com/doc?49924

(1) Flame retardance test may not be applicable to some resistor technologies

Note

(1) Other values may be available, contact factory

Notes

(1) WSL marking (www.vishay.com/doc?30327)

(2) Packaging code: EB (lead (Pb)-free) is non-standard packaging codes designating 1000 piece reels. These non-standard packaging codes

are identical to our standard EA (lead (Pb)-free), except that they have a package quantity of 1000 pieces
