R12.000.3.5 from Reomax, 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 tin-plated end terminal of the non-polarized 1206 fast-acting fuse (3.5A rated current for R12.000.3.5), which opens on overcurrent; interchangeable with the other terminal. |
| 2 | 2 | passive | Second tin-plated end terminal of the non-polarized 1206 fast-acting fuse (3.5A rated current for R12.000.3.5), which opens on overcurrent; interchangeable with the other terminal. |
