0440008.WR from Littelfuse, 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 of two Ag/Ni/Sn end terminations of the 1206 fuse; the fuse is non-polarized, rated 8 A (amp code 008.) at 32 V, with 0.00634 ohm nominal resistance. |
| 2 | 2 | passive | Second end termination of the non-polarized 1206 fuse, interchangeable with the other terminal; the package is 3.2 mm x 1.63 mm with 0.52 mm termination bands. |
