Package_DFN_QFN:QFN-48-1EP_6x6mm_P0.4mm_EP4.4x4.4mm - 3D model: QFN-48(6x6), 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)
