FSMD020-R
Fuzetec Tech · Resettable Fuses · 1812
FSMD020-R from Fuzetec Tech, 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 | One of two interchangeable, non-polarized termination pads (pure tin) of the FSMD020-R PPTC fuse, rated 0.20 A hold, 0.40 A trip, 30 VDC max, 100 A max fault current. |
| 2 | 2 | passive | The other interchangeable, non-polarized termination pad (pure tin) of the FSMD020-R PPTC fuse. The recommended solder pad is 1.78 mm wide (B) with 3.45 mm spacing (A) and 3.50 mm length (C). |
