CAD (KiCad official)

  • Symbol: SL3H7C
  • Footprint: Package_SO:SSOP-4_4.4x2.6mm_P1.27mm
  • 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP 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: sl3h7c-etched.step / sl3h7c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl3h7c.step / sl3h7c.glb are the bare package body.
