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 0.200
(2) Use E24 decade values for 5.0 % tolerance parts and E96 decade values for 0.5 % and 1.0 %. Refer to “Standard Decade” table
