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)
• Temperature range of TCR rating is 0 °C to 150 °C. TCR values are (+) range only with no (-) range values; 1/2 of previous tolerance range
(1) Tight tolerance of 0.5 % is available for resistance values above 0.300 Ω (0402 size) and above 0.200 Ω (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
