**Murata Electronics** · Inductors (SMD) · 0402

LQG15HS18NJ02D 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 18 nH ±5% chip inductor (Q 8 min, DCR 0.36 Ω max, SRF 2200 MHz min, rated current 400 mA); the datasheet does not distinguish the two terminals electrically. |
| 2 | 2 | passive | Second electrode of the 18 nH ±5% chip inductor (Q 8 min, DCR 0.36 Ω max, SRF 2200 MHz min, rated current 400 mA); the datasheet does not distinguish the two terminals electrically. |
