# F12F1.5

**TLC Electronic** · Disposable Fuses · 1206

F12F1.5 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 fast-acting fuse, rated 1.5A and 72V DC with 50A@72Vdc breaking capacity; the fuse is non-polarized so either end can be pin 1. |
| 2 | 2 | passive | Other end-cap terminal of the 1206 fast-acting fuse, rated 1.5A and 72V DC with 240 mOhm typical cold resistance; the fuse is non-polarized and interchangeable with pin 1. |
