SMD0603-025 from BORN, 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 of two interchangeable, non-polarized terminations of the polymer PTC resettable fuse (tin-plated nickel-copper pad); the 025 series is rated I hold 0.25 A, I trip 0.55 A, Imax 35 A, Vmax 9 V or 16 V. |
| 2 | 2 | passive | The second interchangeable, non-polarized termination of the polymer PTC resettable fuse; the 025 series is rated I hold 0.25 A, I trip 0.55 A, Imax 35 A, Vmax 9 V or 16 V. |
