Files

• lm251772rhar.kicad_mod footprint (KiCad)
• lm251772rhar.kicad_sym symbol (KiCad)
• lm251772rhar.step 3D model (STEP, Z-up, seated on z = 0, centred on the footprint origin)
• lm251772rhar.lbr Fusion / EAGLE library part (adom-lbr 2.47.7 from the files above with this page's metadata; no embedded 3D, bind the STEP)

Provenance

• lm251772rhar.kicad_mod and lm251772rhar.kicad_sym: converted from the EAGLE package QFN50P600X600X100-41N (device (default)) in LM251772RHAR.lbr by a direct EAGLE-to-KiCad translation (pad positions, sizes, rotations and paste/mask settings copied exactly; Y axis flipped to KiCad convention). Source .lbr sha256/16 c6fde427e248c667.
• Conversion note: pin-1 dot on EAGLE layer 25 (tNames) mapped to F.SilkS
• Conversion note: added F.CrtYd rectangle -3.88..3.88 x -3.88..3.88 mm (pads + fab outline + 0.25 mm); the EAGLE package had none
• lm251772rhar.step: the 3D model bound to this part in the same Fusion library, byte-identical copy (original sha256/16 cf3840041b4e1804).
• Origin: From the owner's Fusion library A2retro Fusion Designs/LEDster/772PWR/library (the owner's own part). The LM251772RHAR part was originally a SamacSys download (SamacSys terms apply to its geometry).
