SF-1206F200-2 from BOURNS, 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 fuse terminal (Sn-plated end cap) of the 2.00 A fast-acting fuse, rated DC 63 V with 50 A breaking capacity; interchangeable with the other terminal. |
| 2 | 2 | passive | Other fuse terminal (Sn-plated end cap) of the 2.00 A fast-acting fuse, opens within 1 min at 200 % of rated current; typical resistance 40.5 mΩ. |
