**Murata Electronics** · Power Inductors · 1210

DFE322520FD-2R2M=P2 from Murata Electronics, in a 1210. 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 | Inductor terminal 1 (2.2 µH ±20%, DC resistance 46 mΩ max for the 2R2M part), withstand voltage 20 V DC. |
| 2 | 2 | passive | Inductor terminal 2 (non-polarized); rated current is limited by the lower of the 30% inductance-drop or 40 °C temperature-rise value, operating range -40 to +125 °C including self-heating. |
