## CAD (KiCad official)

- Symbol: `CSD87312Q3E`
- Footprint: `Package_SON:VSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm`
- 3D model: VSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN 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: `csd87312q3e-etched.step` / `csd87312q3e-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `csd87312q3e.step` / `csd87312q3e.glb` are the bare package body.
