Files

• 1206l020-30yr.kicad_mod footprint (KiCad)
• 1206l020-30yr.kicad_sym symbol (KiCad)
• 1206l020-30yr.step 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
• 1206l020-30yr.lbr Fusion / EAGLE library part (adom-lbr from the files above with this page's metadata; no embedded 3D, bind the STEP)

Provenance

• 1206l020-30yr.kicad_mod: KiCad Fuse:Fuse_1206_3216Metric footprint (https://gitlab.com/kicad/libraries/kicad-footprints/-/raw/master/Fuse.pretty/Fuse_1206_3216Metric.kicad_mod), unmodified except the 3D model path (now 1206l020-30yr.step). sha256/16 of the original: 8f4307d8c771db71.
• 1206l020-30yr.step: KiCad Fuse.3dshapes/Fuse_1206_3216Metric.step (packages3D), byte-identical copy (sha256/16 5e6dcbe286696143). The footprint's (model (offset 0 0 0) (rotate 0 0 0)), so the STEP is already in the footprint frame and no transform was applied. Checked with OpenCascade (step2glb features): Z-up, seated on the board plane, origin = footprint origin.

• 1206l020-30yr.kicad_sym: KiCad Device:Polyfuse (https://gitlab.com/kicad/libraries/kicad-symbols/-/raw/master/Device.kicad_symdir/Polyfuse.kicad_sym), renamed to the MPN; Value / Footprint / Datasheet / Description set and MPN / Manufacturer / distributor properties added. Graphics and pins unchanged.

Notes

• The Littelfuse 1206L datasheet (pad layout) could not be downloaded from this workspace; the land pattern is KiCad's generic IPC 1206 fuse pattern, not checked against the Littelfuse recommended pads.
