CAD (KiCad official)

  • Symbol: SC92F8482M20U
  • 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: sc92f8482m20u-etched.step / sc92f8482m20u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sc92f8482m20u.step / sc92f8482m20u.glb are the bare package body.
