Retired by Ray on 11 Nov 2026: Retired: this check called a polarised capacitor an unpolarised two-terminal part. Fixed in component-page-verify 0.5.13 (an unrecorded polarity now fails) and 0.5.14 (the datasheet row no longer says unpolarised).

Provenance

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

  • Datasheet: ST Semtech datasheet (3 pp, sha256 d08eb99af23920e1, retrieved 2026-11-06, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
