Pin functions

Pin Function
1 1
2 2

Pin numbering is electrical numbering, viewed according to the manufacturer package drawing. Consult the linked datasheet for absolute maximum ratings, operating conditions, unused-pin handling and assembly limits.

Reusable assets and qualification

The symbol and footprint are supplied as editable KiCad files. The footprint model path is project-relative: place package-reference.step beside the consuming project or update that path explicitly.

Original simplified datasheet-dimension drawing; not manufacturer CAD. Terminal locations are represented; finish, edge contours and lid details are simplified.

This is a development catalog record. Pin mappings come from the manufacturer reference; native import, electrical review, seating/pin-1 overlay review, native model fidelity is not yet qualified. These downloads must not be treated as manufacturing approval.

Sources and license

Original symbol/documentation and original package drawings: MIT (LICENSE). Upstream KiCad footprint/package assets retain CC-BY-SA 4.0 with the KiCad library exception; provenance.json records source URLs and hashes. No manufacturer ownership is claimed for generated or upstream community geometry.

The annotated hero separates nonphysical pad/silkscreen labels from the clean model. The added exact MPN is a virtual identification aid, not a factory marking. Automated marking-fit and geometric-centering checks pass; neither proves package qualification. Editable Fusion library and canonical library JSON are included.
