Pin numbering follows the manufacturer's datasheet. Consult the datasheet for absolute maximum ratings, operating conditions and assembly limits.
Reusable assets and qualification
component.kicad_sym: KiCad symbol, pins numbered as the datasheet.component.kicad_mod: KiCad footprint. Its 3D model path is project-relative: placepackage-reference.stepbeside the consuming project or update the path.package-reference.stepandpackage-reference.glb: the 3D package model.
Footprint drawn from the manufacturer's recommended land pattern (pads 1.90 x 0.64 mm, 1.27 mm pitch, rows 14.60 mm apart). The STEP is an AI-created simplified body (17.55 x 12.20 x 6.00 mm with 24 gull-wing leads) from the datasheet drawing, not manufacturer CAD.
