ASMD1812-200-30V 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 | Tin-plated nickel-copper terminal pad at one end of the non-polarized PTC; rated 30 V dc max, 2.00 A hold, 4.00 A trip at 25°C, 100 A max fault current. |
| 2 | 2 | passive | Tin-plated nickel-copper terminal pad at the opposite end of the non-polarized PTC; interchangeable with the other terminal, same 30 V dc / 2.00 A hold / 4.00 A trip ratings. |
