R12.100.7

Reomax · Disposable Fuses · 1206

R12.100.7 from Reomax, in a 1206. 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 First fuse terminal (silver over-plated with tin end cap, 0.51±0.25 mm wide); the fuse is non-polarized and the two terminals are interchangeable.
2 2 passive Second fuse terminal (silver over-plated with tin end cap, 0.51±0.25 mm wide); the fuse is non-polarized and the two terminals are interchangeable.
