ASMD0603-035 from Shenzhen JDT Fuse, in a 0603. 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 of two interchangeable tin-plated nickel-copper end terminations of the non-polarized resettable PTC; ASMD0603-035 has Ihold 0.35 A at 25°C, with Vmax and Imax as given in the performance table. |
| 2 | 2 | passive | Second interchangeable tin-plated nickel-copper end termination of the non-polarized resettable PTC; ASMD0603-035 has Ihold 0.35 A at 25°C, with Vmax and Imax as given in the performance table. |
