Shenzhen Jinkaisheng Elec · Resettable Fuses · 1812
SMD1812-150 from Shenzhen Jinkaisheng Elec, 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 | Terminal 1 of the non-polarized resettable PTC fuse (tin-plated nickel-copper pad); JSMD1812-150 is rated 8 V max, 100 A Imax, 1.50 A hold, 3.00 A trip. |
| 2 | 2 | passive | Terminal 2 of the non-polarized resettable PTC fuse (tin-plated nickel-copper pad); the device is symmetric, with 0.040 ohm min and 0.160 ohm max resistance (Ri min / R1max). |
