ASMD1812-030-60V from Shenzhen JDT Fuse, 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 | Terminal 1 of the non-polarized resettable PTC fuse (Ihold 0.30 A, Itrip 0.60 A at 25°C, Vmax 60 V dc, Imax 100 A); the two terminals are interchangeable. |
| 2 | 2 | passive | Terminal 2 of the non-polarized resettable PTC fuse (Ihold 0.30 A, Itrip 0.60 A at 25°C, Vmax 60 V dc, Imax 100 A); the two terminals are interchangeable. |
