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

LQG15HS1N2B02D 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 | Terminal electrode at one end of the chip inductor (1.2 nH, ±0.1 nH, rated current 1000 mA, DCR 0.07 Ω max, SRF 6000 MHz min); the end on the polarity-marking side is not identified as pin 1 in the datasheet. |
| 2 | 2 | passive | Terminal electrode at the opposite end of the chip inductor (1.2 nH, ±0.1 nH, rated current 1000 mA, DCR 0.07 Ω max, SRF 6000 MHz min); the inductor is a two-terminal part with electrodes 0.25±0.1 mm wide. |
