CAD (KiCad official)

  • Symbol: ECS-.327-12.5-8X-C
  • Footprint: Crystal:Crystal_C38-LF_D3.0mm_L8.0mm_Vertical
  • 3D model: DT-38 (KiCad packages3D, STEP)
  • 3D model files: ecs-327-12-5-8x-c-etched.step / ecs-327-12-5-8x-c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-327-12-5-8x-c.step / ecs-327-12-5-8x-c.glb are the bare package body.

Provenance

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

  • Datasheet: ECS datasheet (1 pp, sha256 ``, retrieved 2026-10-31, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary crystal numbering (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
