BLM18HE102SN1D 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 single-circuit chip ferrite bead, with 1000 ohm ±25% impedance at 100MHz, 500 ohm min. at 1GHz, and rated current 1000mA at 85°C and 500mA at 125°C. |
| 2 | 2 | passive | Other electrode of the chip ferrite bead, with DC resistance 0.35 ohm max. initially and 0.40 ohm max. after testing, interchangeable with the other terminal. |
