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)
