CAD (KiCad official)

  • Symbol: B3U-1000P
  • Footprint: Adom_Gen:Omron_Electronics_B3_eb9721
  • 3D model: SMD, 3x2.5mm (KiCad packages3D, STEP)
  • 3D model files: b3u-1000p-etched.step / b3u-1000p-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b3u-1000p.step / b3u-1000p.glb are the bare package body.

Provenance

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

  • Datasheet: Omron Electronics datasheet (4 pp, sha256 abb75a2524e2457d, retrieved 2026-11-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
