MF-MSMF075 from BOURNS, in a 1812. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | P1 | passive | First end termination of the PTC resettable fuse; non-polarised, electroless Ni / immersion Au finish; carries up to Imax = 100 A fault current, Vmax = 13.2 V, Ihold = 0.75 A at 23 °C, Rmin = 0.11 Ω, R1max = 0.45 Ω. |
| 2 | P2 | passive | Second end termination of the PTC resettable fuse; non-polarised, electroless Ni / immersion Au finish; electrically identical to pin 1, trips at Itrip = 1.50 A at 23 °C within 8.0 s max, tripped power dissipation 0.8 W. |
