Symbol: MP4835AGRD-T
Footprint: Package_DFN_QFN:QFN-72-1EP_10x10mm_P0.5mm_EP6x6mm
3D model: QFN-72(10x10), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN 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: mp4835agrd-t-etched.step / mp4835agrd-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mp4835agrd-t.step / mp4835agrd-t.glb are the bare package body.
