CAD (KiCad official)

  • Symbol: ECS-TXO-25CSMV-400-BN-TR
  • Footprint: Adom_Gen:ECS_Inc._ECS-TXO-_b387af
  • 3D model: SMD2520-4P (KiCad packages3D, STEP)
  • 3D model files: ecs-txo-25csmv-400-bn-etched.step / ecs-txo-25csmv-400-bn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-txo-25csmv-400-bn.step / ecs-txo-25csmv-400-bn.glb are the bare package body.

Provenance

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

  • Datasheet: ECS datasheet (2 pp, sha256 53687e4059f32039, retrieved 2026-11-12, tier: manufacturer)
  • 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).
