SMD1210-035-24V from TECHFUSE, 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 0.35 A hold-current PPTC resettable fuse (rated 24 Vdc max, 100 A max fault current); the two pads are interchangeable. |
| 2 | 2 | passive | Second terminal pad of the non-polarized PPTC fuse, on the opposite end of the body, with a recommended 1.0 mm x 2.5 mm pad and 2.0 mm pad spacing. |
