046701.5NRHF from Littelfuse, in a 0603. 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 tin-over-nickel-over-copper end termination of the 1.5 A fast-acting thin-film fuse, interchangeable with the other terminal (rated 32 V, opens in 0.2 sec max at 300% of rating). |
| 2 | 2 | passive | The other tin-over-nickel-over-copper end termination of the 1.5 A fast-acting thin-film fuse, interchangeable with the first terminal (rated 32 V, opens in 0.2 sec max at 300% of rating). |
