TECHFUSE · Resettable Fuses · 1206
nSMD005-72V from TECHFUSE, in a 1206. 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 fuse (tin-plated nickel-copper pad), rated 72 Vdc max, 0.05 A hold and 0.15 A trip current at 25°C, with 100 A max fault current. |
| 2 | 2 | passive | Second terminal of the non-polarized PPTC fuse (tin-plated nickel-copper pad), interchangeable with the other terminal, in series with the protected load. |
