CAD (KiCad official)

Symbol: SRC4190IDBR
Footprint: Package_SO:SSOP-28_5.3x10.2mm_P0.65mm
3D model: SSOP-28-208mil (KiCad packages3D, STEP)
3D model files: src4190idbr-etched.step / src4190idbr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); src4190idbr.step / src4190idbr.glb are the bare package body.
