BHFUSE · Resettable Fuses · 1812
BSMD1812-160-24V from BHFUSE, in a 1812. 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 | Unpolarized PTC terminal pad (pad 1.78±0.1 mm wide on a 3.15±0.1 mm pad length, 3.45±0.1 mm pad spacing); the device is symmetric so the terminals are interchangeable. |
| 2 | 2 | passive | Unpolarized PTC terminal pad (pad 1.78±0.1 mm wide on a 3.15±0.1 mm pad length, 3.45±0.1 mm pad spacing); the device is symmetric so the terminals are interchangeable. |
