0805L110ULYR from Littelfuse, in a 0805. 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 non-polarized resettable PTC fuse (0805L110UL: Ihold 1.10 A, Itrip 1.80 A, Vmax 6 Vdc, Imax 50 A), with a 1.00 x 1.50 mm solder pad. |
| 2 | 2 | passive | Other terminal of the non-polarized resettable PTC fuse (0805L110UL: Ihold 1.10 A, Itrip 1.80 A, Vmax 6 Vdc, Imax 50 A), with a 1.00 x 1.50 mm solder pad and 1.20 mm pad gap. |
