**Reomax** · Disposable Fuses · 1206

R12.000.15 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 15A (R12.000.15) fast-acting fuse, which opens on overcurrent; the pad layout shows pads 1.52 mm wide by 2.03 mm. |
| 2 | 2 | passive | Second tin-plated end terminal of the non-polarized fuse, interchangeable with the other terminal; the 1206 body is 3.20±0.20 mm long by 1.60±0.20 mm wide. |
