S1206-SD-6.0A from SART Nanjing Sart Tech, 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 terminal of the two-terminal slow-blow fuse (silver over-plated with tin end termination), rated 6.0A, 63V DC/63V AC, 50A interrupting rating. |
| 2 | 2 | passive | Second terminal of the two-terminal slow-blow fuse (silver over-plated with tin end termination), interchangeable with pin 1 since the fuse is non-polarized. |
