BLM18KG102SH1D 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 two-terminal chip ferrite bead (1000 ohm ±25% at 100MHz, rated current 1000 mA at 85°C and 800 mA at 125°C, DC resistance 0.200 ohm max.). |
| 2 | 2 | passive | Other electrode of the two-terminal chip ferrite bead, connected through the series inductor and resistance element shown in the equivalent circuit (symmetric, non-polarized). |
