0603L150SLYR from Littelfuse, in a 0603. 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 series PPTC element (solder-plated copper end termination), rated Ihold 1.50 A, Itrip 3.00 A, Vmax 6 Vdc and Imax 50 A; the device is not polarized. |
| 2 | 2 | passive | Other terminal of the series PPTC element (solder-plated copper end termination), rated Ihold 1.50 A, Itrip 3.00 A, Vmax 6 Vdc and Imax 50 A; the device is not polarized. |
