F12F4.5

TLC Electronic · Disposable Fuses · 1206

F12F4.5 from TLC Electronic, 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-cap terminal of the 1206 (3.20x1.60 mm) fuse, rated 4.5A and 32V DC with 150A breaking capacity at 32Vdc and about 30 mOhm typical cold resistance.
2 2 passive Other end-cap terminal of the non-polarized fuse (0.50 mm terminal length), interchangeable with the first terminal, with 164 mV typical voltage drop at rated current.
