1206TD-1.5A

prosemi · Disposable Fuses · 1206

1206TD-1.5A from prosemi, 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 terminal of the two-terminal 1206TD-1.5A time-delay chip fuse (1.50 A rating, 0.23 ohm typical cold resistance); the fuse is not polarized and the datasheet gives no pin names.
2 2 passive Second terminal of the two-terminal 1206TD-1.5A time-delay chip fuse (1.50 A rating, 0.23 ohm typical cold resistance); the fuse is not polarized and the datasheet gives no pin names.
