## CAD (KiCad official)

- Symbol: `ECE2DM220F20OTPO`
- Footprint: `Capacitor_THT:CP_Radial_D8.0mm_P3.50mm`
- 3D model: CP_Radial_D8.0mm_P3.50mm (KiCad packages3D, STEP)
- 3D model files: `ece2dm220f20otpo-etched.step` / `ece2dm220f20otpo-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ece2dm220f20otpo.step` / `ece2dm220f20otpo.glb` are the bare package body.

## Provenance

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

- **Datasheet:** [Yunxing datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590182944468856832) (13 pp, sha256 `a29badb837970fa8`, 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).
