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
