CAD (KiCad official)

  • Symbol: 49S-16M-20PF-10PPM
  • Footprint: Crystal:Crystal_HC49-4H_Vertical
  • 3D model: HC-49S (KiCad packages3D, STEP)
  • 3D model files: 49s-16m-20pf-10ppm-etched.step / 49s-16m-20pf-10ppm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 49s-16m-20pf-10ppm.step / 49s-16m-20pf-10ppm.glb are the bare package body.

Provenance

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

  • Datasheet: TKD datasheet (7 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).
