BORN · Resettable Fuses · 1812
SMD1812-050 from BORN, in a 1812. 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 non-polarized PPTC, wired in series with the protected circuit, with I-hold 0.50 A and I-trip 1.00 A at 25°C. |
| 2 | 2 | passive | Second terminal of the non-polarized PPTC, interchangeable with the other terminal, with Vmax 16 V, 30 V or 60 V depending on the suffix and operating temperature -40 °C to +85 °C. |
