**Murata Electronics** · Ferrite Beads · 0402

BLM15BX182SN1D 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 two interchangeable electrodes of the 1800 ohm (±25% at 100MHz) ferrite bead, rated 250 mA max with 0.90 ohm max DC resistance. |
| 2 | 2 | passive | The second interchangeable electrode of the ferrite bead; the equivalent circuit shows a series inductor and resistor between the two terminals. |
