**Murata Electronics** · Power Inductors · 0402

LQW15AN3N3B80D 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 | One of the two end-electrode terminals of the 3.3 nH chip coil (±0.1 nH, Q min 30, DCR 0.030 Ω max, SRF 14.0 GHz min, rated current 2000 mA); the inductor is non-polarized. |
| 2 | 2 | passive | The other end-electrode terminal of the 3.3 nH chip coil (±0.1 nH, Q min 30, DCR 0.030 Ω max, SRF 14.0 GHz min, rated current 2000 mA); the inductor is non-polarized. |
