MF-MSMF020-2

BOURNS · Resettable Fuses · 1812

MF-MSMF020-2 from BOURNS, 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 PTC resettable fuse (MF-MSMF020: Ihold 0.20 A, Itrip 0.40 A, Vmax 30 V, Imax 80 A at 23 °C); the two terminals are interchangeable.
2 2 passive Other terminal of the non-polarized PTC resettable fuse (MF-MSMF020: Ihold 0.20 A, Itrip 0.40 A, Vmax 30 V, Imax 80 A at 23 °C); the two terminals are interchangeable.
