FSMD020-1210-R from Fuzetec Tech, 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 of the non-polarized PTC resettable fuse (pure tin pad); FSMD020-1210-R is rated 0.20 A hold, 0.40 A trip, 30 VDC max, 100 A max fault current. |
| 2 | 2 | passive | Second terminal of the non-polarized PTC resettable fuse (pure tin pad), interchangeable with the other terminal; 0.20 A hold, 0.40 A trip, 30 VDC max. |
