SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: Samsung Electro-Mechanics Specification (Reference Sheet) for CL21A226MAQNNNE, issued MAY.09.2024, downloaded 2026-10-27 from the product page Specsheet link (https://product.samsungsem.com/part/download.do?masterKey=CL21A226MAQNNN&type=specsheet); replaces the JLCPCB/LCSC copy
  • ✓Electrical values agree with the datasheet (p.1, p.2): 22 uF, +/-20%, 25 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 0805): pads at +/-0.95 mm, 1.0 x 1.45 mm, gap 0.9, outer span 2.9. Samsung reflow footprint, MLCC Product Manual 5-4, 2012 (+/-0.15): a 0.81-0.91, b 0.90-1.00, c 1.30-1.40 (a gap, b land length, c land width): gap and land length inside the range, land width 1.45 is 0.05 over (p.34). Pads cover both terminations (band width per p.1); small differences only, KiCad library land kept
  • ✓3D body: plain STEP 2.0 x 1.25 x 1.25 mm against L 2.0+/-0.15, W 1.25+/-0.15, T 1.25+/-0.15 (p.1): all three at nominal; Z-up, seated on z = 0, centred on the pads
  • ✓Distributor numbers kept: DigiKey 1276-2908-2-ND, Mouser 187-CL21A226MAQNNNE; 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
