12F.50000032AG12ZSHGB02 from Xucheng Elec, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One end-cap terminal of the 1206 SMD quick-blow fuse (3.2±0.2 x 1.6±0.2 mm body, 0.5±0.2 mm end cap); the fuse is non-polarized and rated 63V for 250mA to 3A, 32V for 4A to 7A, 24V for 8A to 20A. |
| 2 | 2 | passive | Other end-cap terminal of the 1206 SMD quick-blow fuse; the fuse is non-polarized and the two terminals are interchangeable. |
