ASMD1210-200 from Shenzhen JDT Fuse, in a 1210. 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 terminal pad of the non-polarized resettable PTC fuse (tin-plated nickel-copper, 1.0±0.1 mm pad), rated 2.00 A hold / 4.00 A trip at 25°C, 6 V dc max and 100 A max fault current. |
| 2 | 2 | passive | Second terminal pad of the non-polarized resettable PTC fuse, interchangeable with the other pad, spaced 2.0±0.1 mm from it on a 2.8±0.1 mm wide body. |
