SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: Murata GRM155R71E473JA88-01A reference sheet, specifications as of Jun.17,2026, downloaded 2026-10-27 from the part's spec-sheet link in Murata's product database (pim.murata.com, production status "available"): https://pim.murata.com/asset/pim4/ceramicCapacitorSMD/GRM155R71E473JA88-01A-EN_PDF_CERAMICCAPACITORSMD?lastModifiedDatetime=20260730155533; replaces the JLCPCB/LCSC copy
  • ✓Electrical values agree with the datasheet (p.2): 47000 pF (47 nF), +/-5%, 25 V DC, X7R (+/-15%, -55 to +125 C); the README distributor summary row says the same
  • ✓Pins: two-terminal non-polarized MLCC, pins 1/2 passive with empty names by library convention; symbol, footprint and .lbr agree
  • ✓Pin descriptions use the library wording and cite the dimension drawing (p.2)
  • •Footprint (KiCad 0402): pads at +/-0.48 mm, 0.56 x 0.62 mm, gap 0.4, outer span 1.52. Murata reflow land, Table 2, GRM15 1.0x0.5 (within +/-0.10): a 0.3-0.5, b 0.35-0.45, c 0.4-0.6 (a gap, b land length, c land width): gap inside the range, land 0.56 long (0.11 over) and 0.62 wide (0.02 over) (p.27). Pads cover both terminations (e per p.2); small differences only, KiCad library land kept
  • ✓3D body: plain STEP 1.0 x 0.5 x 0.5 mm against L 1.0+/-0.05, W 0.5+/-0.05, T 0.5+/-0.05 (p.2): all three at nominal; Z-up, seated on z = 0, centred on the pads
  • ✓Distributor numbers kept: DigiKey 490-7762-2-ND, Mouser 81-GRM155R71E473JA8D; both existing product links name Murata and this exact MPN
  • ✓Symbol and footprint Datasheet properties point at the manufacturer datasheet URL
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • ✓component-page-verify: all checks pass

SymbolFootprint3D modelPinsfor all variants
  • ✓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
  • ✓2 of 2 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
