SMD0805-020-33V from TECHFUSE, 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 | Non-polarized PPTC terminal pad (tin-plated nickel-copper); device is rated 33 Vdc max, 0.20 A hold, 0.50 A trip, 100 A max fault current. |
| 2 | 2 | passive | Non-polarized PPTC terminal pad (tin-plated nickel-copper), interchangeable with the other terminal; resistance 0.20 to 8.0 ohm prior to trip, max 8.0 ohm. |
