JK-SMD0603-025-6 from Jinrui Electronic Materials Co, 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 tin-plated nickel-copper terminal pads of the PPTC; device is rated Vmax 6.0 Vdc, Imax 40 A, Ihold 0.25 A and Itrip 0.55 A at 25°C. |
| 2 | 2 | passive | Second interchangeable terminal pad of the PPTC; initial resistance 0.500 to 3.000 Ω, trips within 0.08 s at 8 A, operating temperature -40°C to 85°C. |
