# LP-ISML300

**Wayon** · Resettable Fuses · 0805

LP-ISML300 from Wayon, 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 | First terminal of the non-polarized resettable PTC fuse (IH 3.00 A hold, IT 6.00 A trip at 25°C, Vmax 8 V, Imax 50 A); the drawing shows two identical end terminations. |
| 2 | 2 | passive | Second terminal of the non-polarized resettable PTC fuse (IH 3.00 A hold, IT 6.00 A trip at 25°C, Vmax 8 V, Imax 50 A); the drawing shows two identical end terminations. |
