JSMD0805-150L from Shenzhen Jinkaisheng Elec, 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 | Terminal 1 of the non-polarized PTC device (tin-plated nickel-copper pad); JSMD0805-150L is rated 6.0 V dc max, 50.0 A Imax, 1.5 A hold and 3.0 A trip at 25°C. |
| 2 | 2 | passive | Terminal 2 of the non-polarized PTC device (tin-plated nickel-copper pad); interchangeable with terminal 1, resistance 0.008 ohm min to 0.065 ohm max (R1max one hour post reflow). |
