1206FA-8A from prosemi, 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 termination of the non-polarized 8A fast-acting thick film chip fuse (32Vdc @ 150A / 24Vdc @ 300A interrupting rating, 0.0085 ohm typical cold resistance), connected to a 1.52 x 2.03 mm pad. |
| 2 | 2 | passive | Other end termination of the non-polarized 8A fast-acting thick film chip fuse (typical voltage drop 0.110 V), connected to the second 1.52 x 2.03 mm pad. |
