TECHFUSE · Resettable Fuses · 1210
SMD1210-175 from TECHFUSE, in a 1210. 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 terminal pad (tin-plated nickel-copper) of the PPTC; device is rated Vmax 6 Vdc, Imax 100 A, Ihold 1.75 A and Itrip 3.50 A at 25°C. |
| 2 | 2 | passive | Second non-polarized terminal pad of the PPTC, interchangeable with the other pad; resistance is 0.020 Ω min to 0.080 Ω max (R1max) before tripping at 25°C. |
