Provenance

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

  • Datasheet: KEMET datasheet (23 pp, sha256 af55664a1a1fb7b5, retrieved 2026-10-26, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary two-terminal convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
