BLM21BD102SN1D 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 | One of two electrodes of the single-circuit chip ferrite bead (1000ohm ±25% at 100MHz/20°C, 200mA rated current, 0.40ohm max. DC resistance); the bead is not polarized. |
| 2 | 2 | passive | Other electrode of the single-circuit chip ferrite bead (1000ohm ±25% at 100MHz/20°C, 200mA rated current, 0.40ohm max. DC resistance); the bead is not polarized. |
