Package_DFN_QFN:DHVQFN-16-1EP_2.5x3.5mm_P0.5mm_EP1x2mm - 3D model: DHVQFN-16-EP(2.5x3.5), 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)
