LQG15HN2N2C02D from Murata Electronics, in a 0402. 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 | First electrode of the 2.2 nH ±0.2 nH chip inductor (1.0 x 0.5 mm body), rated 900 mA max, 0.09 Ω max DC resistance; the terminals are interchangeable and the dark marking band only identifies orientation for taping. |
| 2 | 2 | passive | Second electrode of the 2.2 nH ±0.2 nH chip inductor (1.0 x 0.5 mm body), rated 900 mA max, 0.09 Ω max DC resistance, with a self-resonant frequency of 6000 MHz min. |
