**BORN** · Resettable Fuses · 0603

SMD0603-001 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 | Non-polarized tin-plated terminal pad of the SMD0603-001/60N PTC (60 Vdc max, 20 A max fault current, 0.01 A hold, 0.03 A trip at 25°C). |
| 2 | 2 | passive | Second non-polarized tin-plated terminal pad of the SMD0603-001/60N PTC (resistance 15 Ω min to 100 Ω max before tripping, 100 Ω max one hour after reflow). |
