Thick Film Surface Mount Chip Resistors,

Wraparound, Extremely Low Value (0.01  to 0.976 )

DESIGN SUPPORT TOOLS

FEATURES

• Extremely low resistance values 

(0.01  to 0.976 )

• Sulfur resistant (per ASTM B809-95 humid vapor

test)

• Enhanced power rating due to long side terminal

construction (0612, 1020 types)

• Suitable for current sensing and shunts

• Metal glaze on high quality ceramic

• Protective overglaze

• Lead (Pb)-free solder contacts on Ni barrier layer

• AEC-Q200 qualified

• 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” (www.vishay.com/doc?20020)

(1) Tight tolerance of 0.5 % is available for resistance values above 0.300  (0402 size) and above 0.200  (0603 to 2512 sizes)

(2) Use E24 decades only for 5.0 % tolerance. E24 or E96 decades are available for 0.5 % and 1.0 % tolerance. Refer to standard decade table
