CAD (KiCad official)

  • Symbol: PI3A3899ZTAEX
  • Footprint: Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm
  • 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN 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: pi3a3899ztaex-etched.step / pi3a3899ztaex-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pi3a3899ztaex.step / pi3a3899ztaex.glb are the bare package body.
