1210L005WR from Littelfuse, in a 1210. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | P1 | passive | Current-carrying terminal 1 (non-polarized); device holds 0.05 A and trips at 0.15 A (20 °C still air), rated V_max = 30 Vdc, I_max = 10 A, R_1max = 50.00 Ω (measured 1 h after trip or 260 °C/20 s reflow). |
| 2 | P2 | passive | Current-carrying terminal 2 (non-polarized); electrically equivalent to pin 1 - PTC element is symmetric with R_min = 3.600 Ω in initial un-soldered state. |
