Provenance

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

  • Datasheet: TDK datasheet (11 pp, sha256 82669ad15b3e8f71, retrieved 2026-11-05, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
