SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: Samsung Electro-Mechanics Specification (Reference Sheet) for CL31A476MPHNNNE, issued MAY.20.2025, downloaded 2026-10-27 from the product page Specsheet link (https://product.samsungsem.com/part/download.do?masterKey=CL31A476MPHNNN&type=specsheet); replaces the JLCPCB/LCSC copy
  • ✓Electrical values agree with the datasheet (p.1, p.2): 47 uF, +/-20%, 10 V, X5R (-55 to +85 C, +/-15%); 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.1)
  • •Footprint (KiCad 1206): pads at +/-1.475 mm, 1.15 x 1.8 mm, gap 1.8, outer span 4.1. Samsung reflow footprint, MLCC Product Manual 5-4, 3216 (+/-0.20): a 1.64-1.76, b 1.19-1.31, c 1.74-1.86 (a gap, b land length, c land width): land width inside the range, gap 1.80 is 0.04 over and land length 1.15 is 0.04 under (p.33). Pads cover both terminations (band width per p.1); small differences only, KiCad library land kept
  • ✓3D body: plain STEP 3.2 x 1.6 x 1.6 mm against L 3.2+/-0.2, W 1.6+/-0.2, T 1.6+/-0.2 (p.1): all three at nominal; Z-up, seated on z = 0, centred on the pads
  • ✓Distributor numbers kept: DigiKey 1276-3063-2-ND, Mouser 187-CL31A476MPHNNNE; both existing product links name Samsung Electro-Mechanics 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
  • •Not yet checked by a person: land pattern vs datasheet, pin-1/orientation, 3D body vs drawing
