MF-FSMF035X-2 from BOURNS, in a 0603. 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 | A | passive | End terminal 1 of the PTC resettable fuse; device is electrically symmetric - Ihold = 0.35 A, Itrip = 0.75 A, Vmax = 6 V, Imax = 40 A, Rmin = 0.200 Ω, R1max = 1.400 Ω at 23 °C, time to trip ≤ 8 s, tripped power dissipation 0.5 W. |
| 2 | B | passive | End terminal 2 of the PTC resettable fuse; electrically identical to pin 1 - Ihold = 0.35 A, Itrip = 0.75 A, Vmax = 6 V, Imax = 40 A, Rmin = 0.200 Ω, R1max = 1.400 Ω at 23 °C, time to trip ≤ 8 s, tripped power dissipation 0.5 W. |
