12T.00100024AG12S1B02 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 slow-blow SMD fuse (3.2±0.2 x 1.6±0.2 mm body, 0.5±0.2 mm end cap); the fuse is a two-terminal element in series with the protected circuit. |
| 2 | 2 | passive | Other end-cap terminal of the 1206 slow-blow SMD fuse, interchangeable with the first terminal because the drawing shows two identical end caps. |
