046602.5NRHF 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 fuse termination (100% tin over nickel over copper) of the 2.5 A rated element, 32 V max, 50 A @ 32 V AC/DC interrupting rating, 0.023 ohm nominal cold resistance. |
| 2 | 2 | passive | Second fuse termination (100% tin over nickel over copper), interchangeable with the other since the fuse is non-polarized, 2.5 A rated, 32 V max. |
