SMD1210-005 from BORN, 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 | Terminal 1 | passive | One of two interchangeable, non-polarized tin-plated nickel-copper terminals of the resettable PPTC fuse, rated I-hold 0.05 A, I-trip 0.15 A, Vmax 30 Vdc (/30N) or 60 Vdc (/60N), Imax 10 A. |
| 2 | Terminal 2 | passive | The other interchangeable, non-polarized terminal of the PPTC fuse, with the same ratings (I-hold 0.05 A, I-trip 0.15 A, Imax 10 A) and operating range of -40 °C to +85 °C. |
