F1206HI2000V063TM

AEM · Disposable Fuses · 1206

F1206HI2000V063TM from AEM, 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 end termination (silver with nickel and tin plating, B = 0.51 ± 0.25 mm) of the 2.0 A, 63 VDC fuse, nominal cold DCR 0.090 Ω, interrupting rating 50 A at rated voltage.
2 2 passive Opposite end termination of the symmetrical fuse body, interchangeable with the other terminal, with no polarity.
