Thick Film Surface Mount Chip Resistors,
Wraparound, Extremely Low Value (0.01 to 0.976 )
FEATURES
• Extremely low resistance values
(0.01 to 0.976 )
• Suitable for current sensing and shunts
• Metal glaze on high quality ceramic
• Protective overglaze
• Lead (Pb)-free solder contacts on Ni barrier layer
• Material categorization:
For definitions of compliance please see
www.vishay.com/doc?99912
Notes
• Power rating depends on the max. temperature at the solder point, the component placement density and the substrate material.
• Part marking: Reference “Surface Mount Resistor Marking” (document number 20020).
(1) Tight tolerance of 0.5 % is available for resistance values above 0.200 .
