BSMD1812-075-13.2V from BHFUSE, in a 1812. 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 end terminal of the non-polarized resettable PTC fuse (Ihold 0.75 A, Itrip 1.50 A, Vmax 13.2 Vdc, Imax 40 A). |
| 2 | 2 | passive | Other end terminal of the non-polarized resettable PTC fuse, interchangeable with the first terminal (Ihold 0.75 A, Itrip 1.50 A, Vmax 13.2 Vdc, Imax 40 A). |
