BLM21BD151SN1D from Murata Electronics, in a 0805. 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 2.0x1.25 mm chip, in series with the ferrite bead (120-150 ohm class, 150 ohm ±25% at 100MHz); the two terminals are interchangeable. |
| 2 | 2 | passive | Terminal electrode at the other end of the chip; the part is a single-circuit bead with a rated current of 350 mA and a maximum DC resistance of 0.25 ohm (initial). |
