# LQP03TN3N3B02D

**Murata Electronics** · Inductors (SMD) · 0201

LQP03TN3N3B02D from Murata Electronics, in a 0201. 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 terminal electrode of the 3.3 nH ±0.1 nH chip inductor (rated 450 mA max, DC resistance 0.25 Ω max); the datasheet marks one end with a white polarity dot but gives no electrical polarity. |
| 2 | 2 | passive | Second terminal electrode of the 3.3 nH ±0.1 nH chip inductor (rated 450 mA max, DC resistance 0.25 Ω max); the datasheet gives no electrical polarity between the two terminals. |
