F12F20

TLC Electronic · Disposable Fuses · 1206

F12F20 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 Fuse terminal 1 (end cap, 0.50 mm wide on a 3.20±0.20 x 1.60±0.20 mm body); 20A rated current, 32V DC rated voltage, 150A@32Vdc breaking capacity.
2 2 passive Fuse terminal 2 (end cap, 0.50 mm wide on a 3.20±0.20 x 1.60±0.20 mm body); interchangeable with terminal 1, typical cold resistance 1.8 mOhms.
