0470.500DRSNP 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 terminal (Cu/Ni/Sn); 0.500A fast-acting, 125V rated, nominal cold resistance 0.5455 ohm, interrupting rating 50A @ 125VAC/VDC; the fuse is non-polarized and terminals are interchangeable. |
| 2 | 2 | passive | Other fuse terminal (Cu/Ni/Sn); 0.500A fast-acting, 125V rated, nominal cold resistance 0.5455 ohm, interrupting rating 50A @ 125VAC/VDC; the fuse is non-polarized and terminals are interchangeable. |
