28 Oct 2026Claude, at Caleb Taylor's requestValidated against JGHC's S22 Series (SMD2520) crystal sheet (file dated 2024-08-23); 3D model rebuilt to the drawingfiles match
SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: JGHC (Shenzhen Jingguanghua Electronics) S22 Series SMD Seam Sealing Crystal 2.5x2.0x0.55 mm sheet, from the S22 product page on jghcorp.com (https://www.jghcorp.com/Data/0755crystal/upload/file/20240823/S22%E8%B4%B4%E7%89%87%E6%99%B6%E6%8C%AFSMD2520.pdf); 1 page, image only, no revision printed; re-downloaded 2026-10-27 with the same sha256 (e7f0490e...); replaces the JLCPCB copy
  • •Datasheet scope: the sheet covers the S22 series; S2240000091050JY is tied to it by its S22 prefix only (the sheet has no ordering-code key)
  • ✓Pins vs Top View / Top View Crystal Connection (p.1): crystal between pins 1 and 3, GND on pins 2 and 4; pin 1 bottom-left, 2 bottom-right, 3 top-right, 4 top-left (top view) = footprint pads 1 (-0.875, +0.70), 2 (+0.875, +0.70), 3 (+0.875, -0.70), 4 (-0.875, -0.70); bottom view agrees (pin 3 chamfered pad). Renamed pins 2 and 4 G -> GND
  • •Pin types: all passive. Pins 2 and 4 are ground terminals; typed passive to match KiCad's crystal symbol convention (Crystal_GND24 types its ground pins passive), not power_in
  • ✓Descriptions rewritten from the Top View Crystal Connection drawing (p.1), replacing the 'non-polarized two-terminal part' boilerplate
  • •Footprint vs Top View Suggested Layout (p.1): pads 1.15 x 1.00 mm at +/-0.875, +/-0.70 (gaps 0.60 x 0.40) vs suggested 1.0 x 0.9 mm with 0.85 and 0.65 gaps (centres +/-0.925, +/-0.775); both cover the terminals (bottom-view gaps 0.9 and 0.7)
  • ✓Distributors: DigiKey and Mouser carry no S2240000091050JY (searched 2026-10-27); LCSC C555632 kept
  • ✓3D source: tier 1 none (jghcorp.com S22 product page (fetched 2026-10-27 through the jghcorp.com address; www.jghcorp.com did not resolve in DNS from this container) lists only PDF sheets; no STEP published.) Tier 2 rejected (KiCad Crystal.3dshapes/Crystal_SMD_2520-4Pin_2.5x2.0mm.step: 2.50 x 2.00 x 0.83 mm vs 0.55 +/-0.05: out of tolerance.) Tier 3: model rebuilt with the KiCad 3D model generator (gitlab.com/kicad/libraries/kicad-packages3D-generator, commit e272fcc8) from JGHC (Shenzhen Jingguanghua Electronics) S22 Series SMD2520 sheet no revision printed; file dated 2024-08-23, Dimensions and patterns, p.1; parameters in provenance/3d-generator-params.yaml; Adom-authored, CC-BY-SA-4.0
  • ✓3D body vs drawing: body 2.50 x 2.00 mm: 2.50 +/-0.1, 2.00 +/-0.1: pass; overall height 0.55 mm (etched 0.555): 0.55 +/-0.05: pass; pads 0.70 x 0.55 with gaps 0.90 (x) and 0.70 (y): bottom view 0.9 / 0.7: pass (pad size drawing-scaled); pad 3 (3D top-right, KiCad (0.875, -0.70)) carries the 0.3 x 0.3 mm inner-corner chamfer drawn on the bottom view; pads sit inside footprint pads 1-4: pass
  • ✓3D pose: s2240000091050jy.step and s2240000091050jy-etched.step are Z-up, seated on z = 0, centred on the footprint origin (offset 0.0 mm), footprint (model) binding identity (step_pose.py); the source was built in the footprint frame, so the transform is identity; the etched file adds the adom-chip-laser MPN inlay on the top face; GLBs from step2glb convert; footprint (model) path now ${KIPRJMOD}/s2240000091050jy.step with only that line changed (pads untouched); provenance/3d-model.json records source, terms, hashes, transform and checks
  • •3D details not dimensioned on the sheet: terminal pad size (0.70 x 0.55) and the pin-3 chamfer (0.3 x 0.3) are scaled from the bottom view; the chamfer is added by a 20-line extension to the generator (provenance/3d-generator.patch)
  • ✓component-page-verify: all checks pass
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • •Datasheet copy on the page is JGHC's S22 sheet with an OCR text layer added (ocrmypdf), because its drawing labels (pin numbers, GND) are images; the sheet itself is unchanged; JGHC's file sha256 e7f0490eb9efee1a

  • ✓Footprint extracted pad-for-pad from the source board and normalized to the footprint frame (back-side parts un-mirrored)
  • ✓3D model seated z=0 at footprint origin (placement inverse; method centroid-matched to KiCad library models on 59 cases)
  • ✓adom-lbr generate + lint passed
  • ✓4 of 4 pins described from the datasheet (adom-ds2sf, page-cited)
  • •Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
