FEATURES
• 4-terminal design allows for 1 % tolerance
down to 0.0005 and 0.5 % tolerance down to
0.001
• All welded construction of the Power Metal
Strip® resistors are ideal for all types of current Available
sensing, voltage division, and pulse
applications
• Proprietary processing technique produces
extremely low resistance values (down to
0.0005 )
Available
• Sulfur resistance by construction that is
unaffected by high sulfur environments
• Solid
metal
nickel-chrome
Available
or
manganese-copper alloy resistive element with
low TCR (< 20 ppm/°C)
Available
• Very low inductance 0.5 nH to 5 nH
• AEC-Q200 qualified (1)
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Notes
* This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts
with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details

Notes
(1) WSL marking (www.vishay.com/doc?30327)
(2) 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
