MF-MSMF260-2

BOURNS · Resettable Fuses · 1812

MF-MSMF260-2 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 Non-polarized PTC resettable fuse terminal (Ni/Au pad) on one end of the 4532 mm (1812) body; MF-MSMF260 is rated 6.0 V max, 100 A max, Ihold 2.60 A and Itrip 5.20 A at 23 °C.
2 2 passive Non-polarized PTC resettable fuse terminal (Ni/Au pad) on the opposite end of the body; the current path runs between the two pads with 0.015 to 0.080 ohm resistance at 23 °C.

CAD (KiCad official)

  • Symbol: MF-MSMF260-2
  • Footprint: Fuse:Fuse_1812_4532Metric
  • 3D model: 1812, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal 1806 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: mf-msmf260-2-etched.step / mf-msmf260-2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mf-msmf260-2.step / mf-msmf260-2.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: BOURNS datasheet (5 pp, sha256 1cfc3ae1da3d5aed, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
