**TLC Electronic** · Disposable Fuses · 0603

F06T3 from TLC Electronic, in a 0603. 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 0603 time-delay fuse, rated 3 A and 32 V DC with 50 A DC breaking capacity; the fuse is non-polarized. |
| 2 | 2 | passive | Second terminal of the two-terminal 0603 time-delay fuse, interchangeable with the other terminal (typical cold resistance 35 mOhm, typical voltage drop 130 mV). |
