CAD (KiCad official)

  • Symbol: B59252J140B20
  • Footprint: Adom_Gen:TDK_B59252
  • 3D model: Radial (KiCad packages3D, STEP)
  • 3D model files: b59252j140b20-etched.step / b59252j140b20-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b59252j140b20.step / b59252j140b20.glb are the bare package body.

Provenance

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

  • Datasheet: TDK datasheet (11 pp, sha256 a08f145cdda5d6c4, retrieved 2026-11-03, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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).
