BLM18SP300SH1D 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 (30 ohm ±10 at 100MHz, rated 6000 mA at 85°C and 4000 mA at 125°C, 0.008 ohm max DC resistance), interchangeable with the other terminal. |
| 2 | 2 | passive | Other electrode of the two-terminal chip ferrite bead, in series with the inductive and resistive element shown in the equivalent circuit, interchangeable with terminal 1. |
