R12.000.7

Reomax · Disposable Fuses · 1206

R12.000.7 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 One of two interchangeable, non-polarized silver over-plated tin end terminations of the 1206 fast-acting fuse (7A rated current for R12.000.7).
2 2 passive The other interchangeable, non-polarized end termination of the 1206 fast-acting fuse; the pad layout shows two 1.52 mm x 2.03 mm pads.
