# F1206HC30A0TM

**AEM** · Disposable Fuses · 1206

F1206HC30A0TM from AEM, 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 | First terminal of the 30 A, 35 VDC fuse element (silver termination with nickel and tin plating); the device is non-polarized, so the two terminals are interchangeable. |
| 2 | 2 | passive | Second terminal of the 30 A, 35 VDC fuse element (silver termination with nickel and tin plating); the device is non-polarized, so the two terminals are interchangeable. |
