12 100.2 from Shenzhen Jinkaisheng 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 | Fuse terminal 1 (2 A, 12 100.2 rated 72V DC); the drawing shows two 0.51 ±0.25 mm end terminations on a 3.20 x 1.60 mm body, and the fuse is non-polarized. |
| 2 | 2 | passive | Fuse terminal 2 (2 A, 12 100.2 rated 72V DC); the drawing shows two 0.51 ±0.25 mm end terminations on a 3.20 x 1.60 mm body, and the fuse is non-polarized. |
