  • 3D model: 1812 (KiCad packages3D, STEP)
  • 3D model files: 1812l300-etched.step / 1812l300-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1812l300.step / 1812l300.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: LUTE datasheet (11 pp, sha256 139709b0621cd30a, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
