SMD1210-150 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 of the non-polarized PPTC resettable fuse, in series with the protected load, rated Ihold 1.5 A, Itrip 3.0 A, Vmax 6 Vdc, Imax 100 A. |
| 2 | 2 | passive | Second terminal of the non-polarized PPTC resettable fuse, interchangeable with pin 1, with tin-plated nickel-copper pad and 1.0 mm x 2.5 mm recommended solder pad. |
