1206FA-1.5A 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 1206FA-1.5A fast-acting chip fuse (1.50 A rating, 0.249 ohm typical cold resistance, 32Vdc @ 150A / 24Vdc @ 300A interrupting rating); the fuse is non-polarized so either end may be used. |
| 2 | 2 | passive | Other end termination of the 1206FA-1.5A fast-acting chip fuse (0.126x0.064 inch body, 1.52 mm pad gap, 1.5 mm x 2.03 mm pads); the fuse is non-polarized so either end may be used. |
