## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One terminal of the series-connected resettable PPTC fuse (non-polarized, interchangeable with the other terminal); the 0603L025 variants are rated I hold 0.25 A, I trip 0.55 A, Vmax 6 to 24 Vdc and Imax 40 A. |
| 2 | 2 | passive | The other terminal of the series-connected resettable PPTC fuse (non-polarized); the recommended pad is 1.00±0.1 mm x 1.00±0.1 mm with 0.80±0.1 mm between pads. |
