CAD (KiCad official)

  • Symbol: XL2803CD
  • Footprint: Package_SO:SOP-20_7.5x12.8mm_P1.27mm
  • 3D model: SOP-20, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: xl2803cd-etched.step / xl2803cd-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); xl2803cd.step / xl2803cd.glb are the bare package body.
