extremely low resistance values (down to
0.0005 )
• Construction is impervious against high sulfur
environments (ASTM B 809-95 test method)
Available
• Very low inductance 0.5 nH to 5 nH
Available
• Low thermal EMF (< 3 μV/°C)
Available
• AEC-Q200 qualified available (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.
(1) Flame retardance test may not be applicable to some resistor technologies.

(3) Packaging code: EB (lead (Pb)-free) and TB (tin / lead) are non-standard packaging codes that designate 1000 piece reel quantities. 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.
