12F.20000063AG12S1B02 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 x 1.6 mm body), non-polarized, rated 63V for the 250mA to 3A versions, with 12F series opening in 5 s or less at 250% (250mA to 3A) of rated current. |
| 2 | 2 | passive | Other end-cap terminal of the 1206 SMD quick-blow fuse, interchangeable with the first terminal, with 50A breaking capacity at rated voltage and a maximum temperature rise below 135K at 1x rated current. |
