BLM18AG331SN1D from Murata Electronics, in a 0603. 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 electrode of the chip ferrite bead (330 ohm +/-25% at 100MHz, rated 600mA, 0.30 ohm max DC resistance); the bead is non-polarized so the terminals are interchangeable. |
| 2 | 2 | passive | Other electrode of the chip ferrite bead (330 ohm +/-25% at 100MHz, rated 600mA, 0.30 ohm max DC resistance); the bead is non-polarized so the terminals are interchangeable. |
