• I cannot find any information when searching for the SML-31 (1608, t=0.8mm) or SML-51 (1608, t=0.55mm) series.
    • The SML-D1 (1608 size, t=0.5mm, colors: red, orange, yellow, yellow-green, green) and SML-E1 series (1608 size, t=0.35mm, colors: white, blue, blue-green) are the successors to the SML-31 and SML-51 series.
      Even though the shape differs, the new series share the same land pattern dimensions.
      And although neither the SML-31 nor SML-51 series are discontinued, they are currently being supplied to only certain preexisting customers (excluding samples).
