Provenance

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

  • Datasheet: TECH PUBLIC datasheet (5 pp, sha256 fd20d25005ea13a8, retrieved 2026-10-17, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (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).
