LQM21PN3R3MGRD from Murata Electronics, 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 | One terminal of the 3.3µH ±20% inductor; the drawing shows two end terminals (0.5±0.2mm wide) and does not mark polarity, rated current 1.0A at 85°C ambient. |
| 2 | 2 | passive | Other terminal of the 3.3µH ±20% inductor; the drawing shows two end terminals and no polarity, with max DC resistance 0.188Ω and 0.75A rated at 125°C ambient. |
