BLM21AG102SH1D 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 | First electrode of the single-circuit ferrite bead (1000±25% Ω at 100MHz, 0.27Ω max DC resistance at 85°C, 600mA rated current); the part is non-polar and the terminals are interchangeable. |
| 2 | 2 | passive | Second electrode of the single-circuit ferrite bead (1000±25% Ω at 100MHz, 0.27Ω max DC resistance at 85°C, 600mA rated current); the part is non-polar and the terminals are interchangeable. |
